4 Radiological Tests for the Diagnosis of Esophageal Cancer

Cancer of the esophagus originates in the esophageal epithelium, of which it is an anarchic and infiltrating proliferation capable of propagating directly and through the lymphatic and blood channels.

The use of computed tomography largely eliminates the invasive methods of research in deciding the issue of tumor penetration beyond the limits of the esophagus. Computed tomography is used in the diagnosis of metastatic lesions of the liver and lymph nodes in the abdominal cavity.

Ultrasound Test examination:

Ultrasound examination is performed to detect liver metastatic lesions, detect enlarged lymph nodes in regional areas below the diaphragm and accessible areas of the mediastinum, retroperitoneal tissue, assess intra-stenotic tumor spread (when it is possible to carry out an esophageal esophageal transducer for the esophageal narrowing zone).Ultrasound examination of the neck, supraclavicular zones helps to identify metastatic lymph nodes.

X-ray of the upper gastrointestinal:

X-ray of the upper gastrointestinal (GI) tract: X-ray of the upper gastrointestinal tract or upper GI uses a form of real-time X-rays called fluoroscopy and barium contrast material to produce images of the esophagus, stomach, and small intestine. The patient drinks a contrast material that lines the esophagus and stomach, and x-rays are taken. This procedure is also called the upper GI series. The upper GI tract examination that focuses on the esophagus is called a barium swallow or esophagogram examination.

Radiographically, the most common symptoms of esophageal cancer are:

  •         The absence of the esophagus wall at the site of the tumor,
  •         Violation of the relief of the mucous membrane of the esophageal wall,
  •         Filling defect
  •         Narrowing of the lumen or infiltration of the organ wall.

Magnetic Resonance Imaging(MRI):

MRI can be used to see abnormal areas in the brain and spinal cord that may be due to the spread of cancer. And to show the details better, you can inject gadolinium (contrast material) into a vein before doing the study.

Echography to Endoscopy:

This imaging study is beneficial in determining the size of esophageal cancer and whether it has grown to nearby areas. It can also help show if adjacent lymph nodes may be affected by cancer.

Thus, the integrated use of X-ray, esophagoscopy, data from the morphological study of the material in most cases allows to correctly recognize the disease. In some cases, it is necessary to differentiate esophageal cancer with diseases such as cardiospasm, scarring structures of the esophagus, diverticula, benign tumors and ulcers of the esophagus.

Can esophageal cancer be prevented?

As with any disease, it is not possible to prevent esophageal cancer but to help the risks of suffering from it are significantly lower. How? Avoiding the following risk factors:

  •         Avoid the consumption of tobacco and alcoholic beverages.
  •         You must consume healthy foods and maintain a healthy weight.
  •         Reflux treatment can help prevent Barrett's esophagus (a condition in which the lining of the esophagus is damaged by gastric acid) and cancer of the esophagus.
  •         Those who suffer from Tilosis (a hereditary disease that causes excessive growth of the upper layer of the skin of the palms of the hands and soles of the feet) are more likely to develop esophageal cancer.
Ultrasound During Pregnancy - Know What is There to be Known

Ultrasounds at the ultrasound lab have become a regulation for pregnant women these days. So much so, that the women may opt for one from the early weeks as well. But why is it the case? For starters, the powerful technology of ultrasound to see inside the womb can give very useful information in some situations. This is extremely beneficial to see if the pregnancy is miscarried, to measure your baby’s growth, and clarify baby’s position. What is more? An ultrasound test in the labs on a regular basis can also detect the abnormalities of a baby. The scan can also estimate your due date.

For the cases which have detected an abnormality in the baby, the experts offer help and counseling to ascertain the way forward. More often than not the complications in the pregnancy which are found in an ultrasound is addressed only with a pregnancy termination. Very rare is it possible to treat the conditions in the womb because fetal surgery generally causes labour to start.

The safety of an ultrasound test has been the talk of the town for many years now. Though there have been many assurances and corroborations from the medical fraternity which reports that it is absolutely safe, the doubt remains nevertheless. The reason being that there is no high-quality scientific studies that compare the development of children who were exposed and unexposed to modern high-powered ultrasound scans in the womb.

Therefore, as part of a standard operating procedure, the technicians in the Ultrasound Clinic are advised on following the ALARA principle. This basically means that the exposure should be limited to "as low as reasonably achievable".

What you can expect in an Ultrasound scan?

During the first cycle when the pregnancy is confirmed, the ultrasound test would record your baby's heartbeat and that your pregnancy is uterine. This also helps in allaying the fears ectopic or tubular pregnancy which needs to be discussed in detail with the doctors.

Another thing to be noted is that the ultrasound test is done using a cool gel substance which is rubbed into your lower belly. This enables the transducer to better obtain the images as it is moved around the belly. For the pregnant women who are right at the early stages of their pregnancy, the technician may perform a transvaginal (internal) ultrasound, which uses a wand shaped transducer to scan the uterus from the vaginal cavity in order to detect the baby more clearly or earlier than would be possible with a transabdominal ultrasound.

The last word

Despite all the presumptions and analogies, the fact remains that the ultrasound tests are still very much relevant and its counter-effects are all but miniscule. These tests are now available all across the world including countries like India. The tests can also be planned by various online portals which list only the trusted names in the field of diagnostics. Convenience coupled with immediate assistance is what makes these test centers a preferred place for the tests like Ultrasound. 

What is the CT Scan Cost in Delhi?

CT scan Cost Delhi depends upon the part and area of the body and numbers of pictures to be taken. Using CT scan you can diagnose many health problems such as:

·       Pain in abdomen

·       Kidney stones

·       Internal Injuries

·       Infections, blood clots

·       Heart, blood vessels, lungs disorders

·       Urinary tract, bladder, kidney, blockages etc

·       Prostate

·       Bones, joints for ex-wrist, knee, ankle, shoulders etc.

Let’s have a glimpse of some of the most common CT scans.

Mostly CT scan can be performed to detect the injury or disease in the brain. It is also used widely conducted to the abdomen which is known as an abdominal CT scan. A few other CT scans are:

·       CT scan of spleen

·       CT scan of an adrenal gland

·       CT scan of gallbladder and bile duct

·       Used to diagnose tumors in the pancreas

·       Used to diagnose cysts, inflammatory bowel, lung cancer

·       Used to detect bone density, bone disease and spinal disorders

CT scan can successfully diagnose almost every part of your body which is not possible in an ultrasound test that is used to diagnose blood flow and soft body tissues.

Do you know how CT scan diagnoses your body?

Moving X-rays are used in CT scan to examine different parts of your body. The machine produces several images by using x rays by creating a cross-sectional view of slices of body parts such as bones, soft tissues etc. A rotating tube sends X rays into a patient's body during CT scan at CT scan centre. CT scan uses several beams instead of a single beam as in X-ray machine. The moving X-rays create a picture which records on computer. It gives a more concise and detailed view that helps to detect injuries, bleeding and critical illness.

How do you prepare yourself for CT scan test?

It depends on which part of your body is going to be scanned at CT scan centre. Different preparations are needed for different organs.

·       You may be asked to take off your clothes or wear a medical gown provided by test lab if you are required to go for chest CT scan or abdominal CT scan.

·       You are requested to remove all kind of metals wearing on your body like the watch, jewelry, electronic devices and eyeglasses to prevent interface with x-rays.

·        You may be directed to make some special preparation if you are going through some medication.

·       Breastfeeding women ask to avoid breastfeeding for a day after CT scan and if possible try to avoid CT scan.

·       In a few cases, a dye is injected into your body to get contrast image of body parts.

Do you know how many types of CT scans are available at CT scan centre?

Various CT scans are available at CT scan centers like:

  • PET CT Scan: Known as positron emission tomography used in the treatment of cancer disease.
  • Spiral or Helical CT Scan: It is the most advanced CT scan used to develop 3D images instead of 2D images.
  • HRCT (High-Resolution CT Scan): It is used to diagnose inflammation in the lungs.
  • CECT (Contrast Enhanced Computed Tomography): It is used to produce brighter images of an abdominal scan.

CT scan cost depends on the type of scan prescribed by your doctor. CT scan is the most preferred and advanced technology to detect and diagnose critical diseases. 

How do You Prepare Yourself for Ultrasound Test?

The Ultrasound Test is performed to diagnose and reveal several important information lying within your body for the treatment of different disease. The Ultrasound machine uses high-frequency sound waves to generate images of the structures of scanned body parts. This is also known by the name of Sonography.

An ultrasound scan is performed by putting an ultrasound device outside your body while in some cases an ultrasound device needs to be placed inside your body.

Below are the reasons for which you need to go for an ultrasound:

Ultrasound is used to know the condition of your body from the inside. It is used to do several things such as:

·       To check the uterus and ovaries of pregnant women.

·       To check the growth of developing baby inside the womb.

·       To detect gallbladder disease.

·       To check the flow of blood inside your body.

·       In the treatment of a tumor.

·       To diagnose breast lump.

·       To check the thyroid gland.

·       To find out prostate and genital problems.

·        To find out metabolic bone diseases.

·       To help to access joint inflammation.

What is the Risk factor associated with an Ultrasound Scan?

An ultrasound scan is a risk-free procedure that uses low power sound waves. Not any particular is detected till now.  But besides being a valuable machine, it has a few limitations. One of them being that the sound waves could not travel through air and bone. Hence it cannot work well on body parts that contain gases or covered by bones like head and lungs.

How to prepare for Ultrasound Clinic?

There is no specific preparation required for an ultrasound. But a few cases need guidance such as:

·       In the case of gallbladder ultrasound, your doctor may tell you not eat or drink water at least six hours before the exam.

·       While in pelvic ultrasound you will need to drink up to six glass of water and do not go for urination to the examination ends as the full bladder is required.

·       Kids need additional preparation. Once you reach in ultrasound clinic ask your doctor for precautions to be taken.

·       Wear hospital gown or loose clothes.

·       Take off or leave at home all metal jewelry and accessory.

How ultrasound image is produced?

The doctor assigned for the test will apply gel on the area which is to be scanned. The gel restricts the production of air pockets which blocks the sound waves that create images. The gel can be easily removed with cloth or cotton.

The doctor used to press a small device on the area to be scanned to capture images. This small device is known as a transducer. The transducer is used to send sound waves in the body and it captures the image which one will bounce back and then send it computer to take its printout.

In case of a pregnancy ultrasound, a probe is used to combine with the transducer which then inserted into the natural opening of your body to capture images.

An Ultrasound machine plays a revolutionary role in the world of medical science. It is the most convenient way to capture structural images of your internal body parts and helps doctors and surgeons to provide accurate medication and treatment for fast recovery.

No Worries! Ultrasound Test does not Trigger Autism

Ultrasounds during pregnancy can be very exciting as you get to peek at the baby-to-be. But many people have cast aspersions over the technology that uses sound waves; the reason being that there are people who believe in the theory that the sound waves affect a growing fetus. It even had many researchers wondering if the rising rates of autism diagnoses could have anything to do with the increasing number of ultrasound scans that women receive during pregnancy.

But now, a latest research has put this malicious theory aside saying that the children with autism were exposed to fewer ultrasounds during pregnancy, scientists found.

Moreover, the reasons for autism are diverse and they may not be related to the Ultrasound test in labs. Autism is known to have a tendency to flow in families, and scientists have found some of the particular genetic hot spots that may contribute. There are some more factors that contribute to autism such as older parents and maternal obesity. The scientists further believe that a combination of all the aforementioned factors can contribute to autism as well.

So the question arises; could prenatal ultrasounds, which have become more routine and more powerful, be one of those factors?  Now it is true that the scans do use sound waves that penetrate mothers’ bodies, and then collect the waves that bounce back, forming a picture of fetal tissues. As the process is undergone, the waves are probably capable of heating up the tissue they travel through. This is precisely the reason why there have been concerns of autism. But there is no established study that proves that ultrasound might be a contributor.

Nevertheless there are many studies and researches being done which is checking all the aspects of ultrasound depth to ascertain whether there are any bearings that affect fetuses. As a result there is an emphasis to conduct the study right from the start instead of rely on the previous medical records alone. And there is also a need to add certain traits that may influence autism, such as smoking.

For now the people must be greatly assured that ultrasound causes no autism spectrum disorder. This is anything but a matter of great relief who had been fretting over the ultrasound test as being potentially harmful. Rather ultrasound, by the virtue of advanced technology has been instrumental in giving detailed image of the fetus. As a matter of fact, there is no evidence that ultrasound is a primary contributor to poor developmental outcomes when delivered within medical guidelines. While there’s more science to sort out here, the news is reassuring for women who might be worried about getting scanned. Women should follow their doctors’ guidance on ultrasounds.

Ultrasound tests ensure that the possibility of any complications is detected right at the started so the same can be diagnosed well within time. These tests are available in the reputed ultrasound lab across Delhi and NCR. To book your tests, you can even get in touch with the medical test planning centers that give you a detailed list of such labs in quick time. 

Why You might Need an Ultrasound for Heart?

An average person would always relate the ultrasound Test the examination wherein the hard tissues of the body are to be detected. Some of them may also be of the opinion that the ultrasound test is done to check the fetus health inside mother's womb. An ultrasound of heart is relatively less known test and yet one cannot downplay its importance in detecting the heart ailments. An ultrasound clinic is the place to go to for the test. Let us take a look as to what are the conditions of the heart that can be detected by a heart ultrasound.

One of the most common problems has been the heart murmurs. Similarly, to diagnose and determine the valve condition, ultrasound test is very much required. Other minor and major conditions wherein you have to go for ultrasound are:

·        Detection of the presence of abnormalities in heart's structure.

·        Size and thickness measurement of the heart and its chamber.

·        Ultrasound for heart is also done to examine the motion of the chamber walls and the extent of damage which has been caused to the heart muscle post heart attack.

·        Assessment with regard to how different parts of the heart are functioning in patients with chronic heart disease

·        Look for Congestive Heart Problems. Also the presence of tumor in the heart can be identified in the same test.

·        Assess for and monitor congenital defects

·        Evaluation of blood flow through the heart is also done in the ultrasound lab.

·        In the pre-heart transplant cases, the ultrasound test check for the major blood vessels have been damaged by traumatic injury

·        Cardiomyopathy, a problem in the heart muscle can also be determined.

·        The heart might suffer from the problem of abnormal heart rhythms known as arrythmias

·        Assess EF –ejection fraction levels (heart flow)

Moreover, the ultrasound lab can also rule out these abnormalities.

Popularity of heart ultrasound

There are several reasons that contribute to the popularity heart ultrasound (also known as cardiac ultrasound). Other than being a test which does not involve a sedative for echo, ultrasound for heart is:

·         It does not involve the injection of a dye in a regular echo. It can be used to enhance an echo (contrast echo), but it is hardly a necessity for all echocardiograms.

·        Unlike MRI scan, the patient is not put into a closed chamber table at the time of the procedure. Echo is conducted whilst the patient lies on a comfortable table.

·        The ultrasound lab always has the availability of Echo scanning equipment that uses the advanced technology. This technology may not be available in every healthcare setting.

·        This is the most accepted procedure of diagnosis of heart health, a variety of heart diseases and ailments. Age is not a factor when it comes to the use of echo in any stage of life.

·        There is zero involvement of radiation exposure in the echo.

Given the fact that over millions of people in the world succumbs to heart failure and other similar ailments, the cardiac ultrasound must be conducted whenever needed. 

What Ensures a Good Sonogram Image?

For a pregnant woman, the images of sonogram matters the most and why not? After all they give a sneak peek of what the baby may look like. In this age of social media many Ultrasound Clinic have also created online groups for sharing the ultrasound images which make the ladies drool over them. In the last 4-5 years elective ultrasound has become increasingly popular as more mothers want to see their baby’s face before he/she is born. And thanks to recent advances in technology, ultrasound machines can render 3D and 4D imaging that is more lifelike than ever before. But, there is something to be very specific about; that the two expecting mothers do not have the same wombs and the 3D images of sonogram does get influenced by the same. There are quite a lot of factors that influence the clarity of ultrasound photos. I am going to list the top 5 in order of importance below:

1.     The Location of the Placenta- Your placenta is the organ that develops inside your uterus during pregnancy that provides oxygen and nutrients to your growing baby. The placenta is attached to the uterine wall either in the front (called an anterior placenta), or in the back (a posterior placenta). If you have an anterior placenta, it will be over the top of baby’s face, making it harder to get clear photos. Therefore, the recommended timeframe to get 3D/4D imaging is at 28-34 weeks, before baby gets too big and squished into the placenta. If your placenta is posterior, it will be under the baby, and you can wait until 34-38 weeks to have your ultrasound. If you don’t know where your placenta is located, you can email us an ultrasound picture from your anatomy scan, and we can tell you.

2.     The amount of amniotic fluid- A higher amount of fluid present in the amniotic sac would ensure that the 3D/4D imaging is clear. Higher fluid levels are especially important if you have an anterior placenta because we need to have fluid between baby’s face and the placenta to be able to get images. To make sure you have fluid in the amniotic sac, it is recommended that you drink 65 to 80 ounces of water a day, every day, the week leading up to your ultrasound appointment.

3.     The position of the baby- It is ideal that your baby is head down (meaning the head is down low near your cervix). This is the position baby should be in before you go into labor. This position also yields the best 3D/4D imaging in the Ultrasound Test. The baby’s face should also be pointing upwards towards your stomach. If baby is looking towards your spine it would be impossible to get images. Babies in the breach position i.e. the gaping position are also harder to get images of, especially with an anterior placenta.

4.     The make and model of the Ultrasound Machine- Just like any other technology, the newer more modern devices and equipment produce better quality imaging. There are several major manufacturers of ultrasound machines. The leading brands offer the latest cutting-edge 3D/4D and high definition ultrasound technology. Ultrasound facilities that use newer, updated machines in the Ultrasound labs Delhi can provide you with better imaging of your baby.

5.     The experience of the sonographer- Learning to do ultrasounds is not an easy endeavor. Extensive professional training and several years of hands on practice is required to gain the experience necessary to acquire clear 3D/4D imaging. Additionally, the ultrasound tech should be knowledgeable about the tricks to get baby in the right position for photos. You’ll want to choose a facility that has an experienced tech who has performed, not just hundreds, but thousands of ultrasounds.

Follicular Ultrasound Monitoring: What is it?

Ultrasound is the best way to follow the response of the ovaries to stimulation therapy, either pure or for PMA.

It can be done through the abdominal wall and, in this case, the bladder must be full. It is more often now vaginally.

It allows counting the follicles developing on the surface of each of the ovaries. Each follicle contains an oocyte: as soon as it reaches 17/18 mm in diameter it is likely to ovulate. The professionalism of the sonographer is therefore decisive for a proper accounting of the follicles.

Ultrasound Test also allows appreciating the thickness of the endometrium, the coating inside the uterus. The endometrium must thicken to be ready to receive the embryo. At the time of ovulation, its thickness should be at least 8 mm.

Finally, it allows visualizing the vascularization of the myometrium, a witness of the quality of the uterine tissue.

It is a simple test which consists of performing a series of ultrasound generally between 2 to 4 controls, implemented in successive days via trans-vaginal.

What is it for?

It is used to evaluate the internal genitalia and the changes that occur throughout the ovulatory cycle in a woman of childbearing age. This allows Ultrasound Clinics to verify if the woman ovulates or not, and the exact moment when this happens.

Parameters that are controlled by ultrasound in follicular monitoring:

Uterus: its position, size, and characteristics.

Ovaries: the number of follicles of each ovary and their growth is observed. Each follicle of the ovary grows throughout the cycle until it burst at the time of ovulation and expel the ovule(s); In general, when they are mature, they measure between 19 and 22 mm. Ultrasonographically, if ovulation occurs, direct signs of ovulation are visualized, which would be the disappearance of the follicle or the flattening and irregularities of the wall of the follicle and indirect signs such as the presence of liquid in the pouch of Douglas.

Endometrium: is the layer of tissue that lines the inside of the uterine cavity. This tissue grows all cycles, preparing to receive the embryo that must be implanted, or falls at the time of menstruation. Its optimal growth must exceed at least 7mm at the time of implantation.

Cervical canal: near the time of ovulation in the canal of the cervix produces mucus that becomes abundant.

Folliculometry is monitoring the maturation processes and the growth of the endometrium in the first phase of the menstrual cycle and revealing signs of ovulation that occurred (the egg is released from the ovary) in the second phase of the period.

 

When do we use folliculometry?

Folliculometry is an additional method, and it does not replace either rectal temperature, hormonal studies, or ovulation tests. All these data are evaluated individually and in a complex. Folliculometry is a diagnostic method, and it is combined with homeopathy courses, especially for pregnancy planning, osteopathy, and all health procedures.

Elaborate Information on Ultrasound and Its Types

We all have a fair idea about what an ultrasound is. It is a test done using high-frequency sound waves that create images of the internal portion of the body. This test has been commonly used for checking any health updates at the time of pregnancy. Ultrasound tests, or sonography, unlike other tests are considered to be a much safer option because it merely uses the sound waves that echoes on the area of diagnosis thereby resulting in no radiation-like effects.  These scans are done in the Ultrasound Clinicto evaluate fetal development. Alternatively, they can also be recommended by the physicians to for checking other internal organ's ailments such as liver, heart, kidney, or abdomen. An ultrasound test is equally adept at performing certain types of biopsy.  

The image produced by the Ultrasound Test is known as sonogram.

Quick facts on ultrasound scans

Given below are some of the key things to remember about ultrasound.

·        Due to the high safety standards, Ultrasound scans are widely recommended.

·        Its most common use is seen for checking the progress of a pregnancy.

·        It is used to enhance the diagnosis of the treatment.

·        No special preparation is normally necessary before an ultrasound scan.

Concept

Ultrasound scans are carried out by a sonographer.

The person who performs an ultrasound scan is called a sonographer, but the images are interpreted by radiologists, cardiologists, or other specialists.

At the time of the sonography, the sonographer uses a device known as transducer, a hand-held device, which is placed on the patient's skin. The ultrasound waves then travel through the soft tissues of the body. It does not get absorbed but it rather bounces back or echoes off to the denser surfaces thereby obtaining an image in the process.

It is named as ultrasound as the sound is produced in a frequency which is not audible to the normal human ears.

The frequency of ultrasound in all the ultrasound in delhi is between 2 and 18 megahertz (MHz).

It has been observed that the higher frequency of an ultrasound enables better quality images and is readily absorbed by the skin and other internal tissue. Hence they cannot penetrate as deeply as lower frequencies. Yet its use is deemed fit because the lower frequencies fail to penetrate deep into the tissues.

How Does it Capture an Image?

The ultrasound waves travel through blood. For instance if the waves hit the heart valve, it would bounce back.

Similarly, if the ultrasound test is for gallbladder and there are gallstones present in the organ then the waves would bounce back from them and create an image.

This bouncing back, or echo, gives the ultrasound image its features. Varying shades of gray reflect different densities.

What Does a Transducer Look Like?

A transducer is more like a wand in appearance and is placed on the body which is to be checked for.  Some of the tranducer are used for internal use for clearer and informative images as well. These are:

·        an endovaginal transducer, for use in the vagina

·        an endorectal transducer. This is used for getting images of the rectum

·        a transesophageal transducer. It is passed down the patient's throat to examine the esophagus.

The Ultrasound Lab also has small transducers that can be positioned onto the end of a catheter and inserted into blood vessels to examine the walls of blood vessels.

They are used for diagnosis, for treatment and also for guidance during the procedures of biopsies. Due to its high penetration power, it can be also used for internal organs such as the liver and kidneys, the pancreas, the thyroid gland, the testes and the ovaries, and others.

Other critical problems that can be brought into notice are:

·        Lump of a tumor. This could be cancerous, or a fluid-filled cyst.

·        An ultrasound can successfully diagnose the problems related to soft tissues, muscles, blood vessels, tendons, and joints.

·         The test is also effective in looking into certain conditions such as a frozen shoulder, tennis elbow, carpal tunnel syndrome and others.

Circulatory problems

Doppler ultrasound, a form of ultrasound done in the lab assesses the follow of blood in a vessel and blood pressure. The speed of the blood flow or any kind of obstruction can also be determined in an ultrasound test.

An echocardiogram (ECG) is an example of Doppler ultrasound. It is brought into effect in order to create images of the cardiovascular system and to measure blood flow and cardiac tissue movement at specific points.

A Doppler ultrasound can also give us the required assessment with regard to the functioning and state of cardiac valve areas, any abnormalities in the heart, valvular regurgitation, or blood leaking from valves, and it can show how well the heart pumps out blood.

It can also be used to:

·        examine the walls of blood vessels

·        check for DVT or an aneurysm

·        check fetal heart and heartbeat

·        evaluate for plaque buildup and clots

·        assess for blockages or narrowing of arteries

Ultrasound has various forms. One such form is carotid ultra-sonography that may include a Doppler ultrasound. This would reveal how blood cells move through the carotid arteries.

Ultrasound in anesthesiology

Ultrasound has been a test of choice for the anesthetists to guide a needle with anesthetic solutions near nerves.  

Ultrasound in emergency medicine

Some other common uses of ultrasound test in various conditions include:

·        traumatic injuries

·        pericardial tamponade

·        fluid buildup around the heart

·        hemoperitoneum, or blood leakage in the abdomen

Abdominal sonography

For abdominal gastroenterology, the method of ultrasound is used by the gastroenterologist to get the images of the spleen, kidneys, bile ducts, gall bladder, liver, aorta, inferior vena cava, pancreas, and other solid organs located in the abdomen.

The evaluation for suspected gallstones or inflammation of the gall bladder, known as cholecystitis is also done by the help of ultrasound.

It can detect if the appendix is swollen or inflamed, which would suggest appendicitis. Blood work would confirm an infection.

But in cases there is an accumulation of fat in the body or gas formation in the bowel; it may block the ultrasound waves at times thereby causing difficulties in diagnosis.

Newborn infants

The Ultrasound test can be performed by a sonographer by placing the probe on the i.e. the soft spot on the top of the skull.

This helps in detecting any sort of abnormalities such as

·        hydrocehalus,

·        periventricular leukomalacia, a form of white-matter brain injury.

With the fontanelle growing smaller in time, it leads to the production of bad quality images.

Obstetric ultrasonography

Ultrasound devices release high-frequency sound waves from the transducer which helps in getting the images of the internal part of the body in conditions like pregnancy.

Ultrasound is part of standard prenatal care. They collect the images of the fetus or embryo in the uterus.

Obstetric ultrasonography can reveal various aspects of both fetal and maternal health. It can also help doctors assess the progress of the pregnancy.

The device known as transducer is typically placed on the mother's abdomen. But some special conditions require the device to be placed in the vagina.

A transvaginal scan provides the most detailed pictures of early pregnancy and it is considered to be a better option if the mother has obesity.

 Doppler sonography shows the fetal heartbeat. It equally comes in handy as a test that finds out the signs of abnormalities in the heart and blood vessels.

Ultrasound and urology

·        In urology, ultrasound can check:

·        how much urine remains in the bladder after urinating

·        the exact conditions of the critical organ's health like those of the pelvic region, including the uterus and testicles

In young, adult males, ultrasound can distinguish different types of swelling from testicular cancer.

Pelvic sonographies can be internal or external.

In cases of the male, the internal sonogram is done by inserting the device into the rectum. The same device is inserted into vagina of the female.

This can provide information about the prostate gland, ovaries, or uterus.

The ultrasound in delhi done for the pelvic floor to assist the doctors in correct diagnosis and to ascertain the extent of conditions like a pelvic prolapse, incontinence or obstructed defecation.

Musculoskeletal Sonography

Ultrasound can be further used for the examinations of the ligaments, bone surfaces, soft tissue masses, nerves, muscles, and tendons.

What to Expect

An ultrasound is done at the Ultrasound clinic under the guidance of a specialist and a doctor. Usually these scans do not take more than 20 to 60 seconds. It is a painless scan and creates no noise.

·        By and large there is no special preparation needed. In most cases, no special preparation is needed, but patients may feel the necessity to wear loose-fitting and comfortable clothing.

·        If a person is suffering liver or gallbladder condition, the patient may have to fast for several hours before the procedure.

·        In early stage pregnancy scan situations, the patient is required to drink plenty of water and try to avoid urinating for some time prior to the test.

·        The scan produces better images of the uterus when the bladder is full.

·        The scan usually takes place in the radiology department of a hospital. A doctor or a specially-trained sonographer will carry out the test.

External Ultrasound

The sonographer puts a lubricating gel onto the patient's skin and places a transducer over the lubricated skin.

·        The transducer is then moved on the part of the body needing examination. The common examples are those of a patient's heart or a fetus in the uterus.

·        The patient is unlikely to feel any discomfort or pain. They would merely feel the transducer moving over the skin.

·        During pregnancy, a slight discomfort is caused because of the full bladder.

Internal Ultrasound

If there is a need for an evaluation of an internal organ for a possible abnormality or pain, the transducer would be placed in the rectum for a man and in the vagina for a woman. The parts of the digestive system, for instance the esophagus, the chest lymph nodes, or the stomach, an endoscope may be used.

·        For obtaining the images of the internal organs, the ultrasound device is attached to the end of the endoscope along with a light and inserted into the patient's body through the mouth.

·        For any case in which the patient is suffering from pain, the doctors may provide medication to release the pain.

·        Internal ultrasound scans are less comfortable than external ones with a slight risk of internal bleeding.

Safety

As it has been clear thus far, most of the ultrasound is noninvasive involving no ionizing radiation exposure. The procedure is believed to be very safe. However, since the long-term risks are not established, unnecessary "keepsake" scans during pregnancy are not encouraged. Ultrasound during pregnancy is recommended only it has been called for medically.

Since the test uses a coat of latex on the body part requiring ultrasound. Therefore the person who is allergic to latex should notify the doctors about the same.

Cost of the Ultrasound Scan

Purpose of Ultrasound Test

What is an ultrasound?

Ultrasound is a test that has been largely associated with pregnancy. It is rather a common sight to carry out ultrasound test in the hospitals with ultrasound laboratory in Delhi in order to find out the gender of the baby and also to identify the anomalies or birth defects early on. But fetal imaging is only one of the common uses for ultrasounds.

How does the procedure work?

An ultrasound can develop a live image of the inside of the body using sound waves in an ultrasound lab in Delhi. This is done by using a tool called a transducer which produces high frequency sounds that human ears cannot process and then uses the echoes to discover all the information about the organs and tissues inside. This information is then shown on a computer screen. It takes a trained ultrasound technician to be able to perform the test properly. Once the test is done, a radiologist or doctor can interpret the images in order to diagnose conditions.

What is an ultrasound used for?

An ultrasound has many different uses, but here are the most common:

  1.      Pregnancy: In the beginning of the pregnancy an ultrasound image can be used to confirm pregnancy and reveal due dates. As the pregnancy progresses it can be used to determine the presence of twins and reveal the gender of the baby. And ultrasound can also be used to find out any problems like birth defects, breech positioning, ectopic pregnancies, issues with the placenta, and more.​
  2.      Diagnostics: Ultrasound imaging is often used to find out issues that include the heart and blood vessels, gallbladder, kidneys, bladder, ovaries, uterus, liver and basically any organ inside the body. This procedure is also used to perform a thyroid biopsy or a breast biopsy to determine if there is a presence of cancer. Doctors also use this imaging to help guide the biopsy needle through the skin to a very precise area in order to retrieve tissue to test.

What are the different types of ultrasound?

Most of the time an ultrasound can be successfully done using the transducer on top of skin. However, if this does not produce a clear picture the technician use a special transducer in one of the body's openings.

What are the benefits of ultrasound?

  • They are painless and do not require needles or incisions, although the transducer wand can sometimes be uncomfortable.​
  • There is no use of radiation which makes these tests safer than X-rays, CT scans or an MRI. There are absolutely no harmful side effects.​
  • Soft tissues don't show it very well in the next day but very clearly in an ultrasound image.​
    They are easily accessible and cost less and other techniques.​

What is expected during ultrasound?

At times the doctor may issue instructions such is not eating or drinking or wearing lotion or perfume before the test. You may need to drink several glasses if your bladder needs to be full. You will also be given a gown for wearing so that the ultrasound technician can easily maneuver the transducer in the area which will be screened. 

You will be down on the bed and the ultrasound tech will use a water-based gel so that the transducer can make contact with the skin without allowing for any air between; the measurements, notes, and still images maybe taken during the process. 

While an MRI can take up to two hours, an ultrasound can take anywhere from 10 minutes to about one hour. You will be awake and alert for the entire process, and the technician will often be able to show you on the computer what they are seeing. 

How much will an ultrasound cost?

There are two things that need to be considered while getting a fair idea as to what the ultrasound cost in Delhi is. The first point is of course the fact that it depends mostly on the part of the body which has to be examined in the ultrasound test. Next, given the fact that India is a diverse country multi-tier facility like super specialty hospitals and nursing homes, the prices vary. Ideally, the cost of ultrasound ranges between INR 500 and 3200.
