Myths And Realities Of Computed Tomography

For the prevention, diagnosis and treatment of diseases there are various medical technologies such as ultrasound and computed tomography, which allow the doctor to know the health status of a patient.

ct-scan-head

Computed Tomography (CT) is an advanced medical equipment with which images are obtained through the combination of x-rays (x-rays) and computed technology that allows cross-sections (horizontal and vertical) to be obtained from any area of ​​the body.

The advantage of this technology is the quality and detail of the images of bones, muscles and organs, which is why it is frequently used for the diagnosis of cancer and heart disease. Before having a CT scan, it is suggested to know the CT scan head cost in Delhi.

For the diagnosis of cancer, Dr. José Hinojosa, head of Radiotherapy at the Cancer Centre of the ABC Hospital, said that together with the pathological examinations, the images help to characterize the tumour, which allows, among other diagnostic elements, identify if the patient is a candidate for operation.

However, when a patient is asked for a tomography study, there are doubts and fears about this type of procedure, below we share some myths and realities about the CT scans.

Myth 1

The tomography hurts.

Reality

Computed tomography does not cause pain, it is even a study that can be performed on an outpatient basis, unless it is part of the treatment of an inpatient.

Myth 2

Tomography causes radiation.

Reality

With the technological advancement, equipment such as the Philips Ingenuity CT, have managed to reduce radiation to the patient by up to 80%. More radiation is received in a morning sunbathing on the beach than in a CT scan.

Myth 3

Tomography is a complicated procedure.

Reality

It is a very simple procedure, where specialized personnel attend and instruct the patient at all times. Alejandro Sampedro, a 22-year-old patient, commented “during the first scan I was afraid, however I learned that the important thing is to live the experience in a relaxed way, be with yourself and especially cooperate with the medical staff to facilitate your work and have a better Outcome. It is, in short, a simple procedure. ”

It is important to be assured that the medical staff is on the lookout for the patient throughout the procedure and that the sounds and movements of the scanner are to emit low doses of x-rays that, absorbed by the body and detected by the scanner, will result in Reliable images that the doctor will have to make an accurate diagnosis.

So if you have doubts about any symptoms, do not forget to go to the CT scan centre in Noida, and it is even better to consult it when nothing hurts because prevention is always better and cheaper. You have to overcome the fear of the great devices that have been created to help take care of your health.

Alzheimer's Diagnosis, What Are The Differences Between A Resonance, A CT Scan And A Cerebral PET?

Magnetic resonance imaging, Computed Axial Tomography (CT) or Positron Emission Tomography (PET) are three neuroimaging tests that allow us to obtain 3D brain images and high resolution. Neurologists can request them to confirm a diagnosis of Alzheimer's disease and rule out other causes that may be behind cognitive disorders such as memory loss.

computed-tomography

When we talk about these tests, the image that comes to mind is that of diagnostic testing which we have to be completely still, lying down and with our heads inside a donut-shaped device. Although the machine and a part of the procedure are similar, the three tests are different and offer us different information.

Here are the most significant differences between them:

Magnetic resonance

It works with a magnet. To get an idea of ​​its power, a 3 Tesla magnetic resonance is equipped with a magnetic field 60,000 times more powerful than Earth's. This magnetic field is combined with radio pulses to detect the magnetic characteristics of the body's hydrogen atoms, and thus be able to send the computer the information necessary to reproduce the brain image.

Provides comprehensive information of soft tissues. It is one of the most used techniques in research since it allows to obtain high-resolution images, with detail of up to 0.4 millimeters, in the case for example, of resonance of 3 Teslas.

It is harmless, does not produce ionizing radiation. Therefore, and due to the magnetic field, it is only contraindicated in people who have a pacemaker or metal implants.

The test usually lasts more than 30 minutes. The person inside the machine must be still during the entire acquisition.

It is a very noisy test. The sound comes from the vibration of the gradient coils, produced by the alternative passage of the current needed to scan.

CT

It works with an x-ray beam. The scanner allows obtaining multiple images, taken from different angles, from the absorption made by the different tissues to X-rays.

It offers bone, soft tissue, and air images. Its resolution in soft tissues is lower than that of magnetic resonance.

It emits small ionizing radiation. The risk of developing cancer due to radiation is negligible. However, it is not recommended to repeat the test excessively and its use is only prescribed in children when it is strictly necessary. Nor is it recommended for pregnant women, because of the risk that it may affect the foetus.

Some tests can be done in just 10 minutes. The person inside the machine must also be still during the entire acquisition. It is suggested to know the CT scan price in Delhi first, before having a CT scan.

Brain PET

It works with a radioactive tracer that is administered intravenously before testing. To take the images, the PET machine also incorporates a CT scan or an MRI.

Provides information about biological processes. Thanks to the contrast substances contained in the tracer, it allows obtaining high definition images to assess aspects such as, for example, the consumption of glucose in the brain, which indicates the activity of different areas or to detect the characteristic amyloid protein deposits of Alzheimer's disease.

It also uses ionizing radiation. Therefore, the best CT scan in Delhi is not recommended for pregnant women.

Medical Diagnostics: CT or MRI? Specialist Explains

It is impossible to imagine modern diagnostics without such imaging methods as computed (CT) and magnetic resonance imaging (MRI). But many patients do not know how CT differs from MRI, and sometimes mistakenly believe that the difference is only in price.

Medical Diagnostics: CT or MRI? Specialist explains

Photos from the Internet

That is, if the MRI is more expensive, then it is more informative. In fact, two of these studies are based on various physical processes. Based on this, each of them is good at the study of certain pathologies.

So, in computed tomography, as well as in a conventional X-ray examination, the property of X-ray radiation is absorbed, depending on the density of body tissues. Just CT is a multilayer x-ray, and it gives the opportunity to three-dimensional research. It is suggested to first know the CT scan cost Delhi.

In MRI, a powerful magnetic field (nuclear magnetic resonance) is used. The tomography sends electromagnetic pulses, and the effect that occurs in the body is captured by the equipment and processed into three-dimensional images.

In what cases is CT diagnostics used, and in which cases an MRI scan is necessary?

The tumours of the brain and spinal cord, soft tissues are better visualized with MRI, however, in order to detect if there are metastases, CT. Computed tomography is also necessary for examining the skeletal system of the body and for identifying any pathologies of the lungs.

Everything else depends on the pathology. For example, degenerative pathologies of the brain, diseases of the spinal cord - these are MRI. Aneurysms of the arteries of the brain- CT angiography needs to be done to plan the operation further. The heart, coronary vessels are also examined using CT. Diffuse pathologies of the heart, myocarditis, cardiomyopathy, etc. Already need to be examined with an MRI.

The tumours of the pelvic organs are mainly examined using MRI, but to detect the prevalence of the process, CT should be done- it is faster, cheaper and more informative. A CT scan with intravenous contrast is done. At high speed, contrast is introduced, it stains all the organs and structures that interest us, and makes it possible to differentiate different diseases.

In general, CT is a diagnostic method for studying very many pathologies, starting from the head, ending with the lower extremities. This can be either an urgent study – poly-trauma, dissection or rupture of aortic aneurysms, or planned: for cancer, when multiple organ studies are done to get all the information about metastasis, about dynamic changes after chemotherapy courses to plan further treatment. CT is also used for postoperative dynamic monitoring.

Cardiac surgery and invasive cardiology also cannot do without CT: a screening study of the coronary vessels of the heart is done to detect stenosis and dissection and other aortic diseases. CT, according to the specialist, is also used in bowel examination. Today contrast diagnostic test is done with filling the intestines with X-ray negative contrast for the study of all layers of the intestine.

A CT scan in best CT scan centre in Delhi is carried out for children from the first birthdays about heart defects, as well as intrauterine and birth injuries, congenital diseases. There is close cooperation with paediatric cardiac and neurosurgery.

Can Diabetes Change The Physical Appearance?

It is known to one and all that diabetes is called a silent killer because of the way it affects the vital organs of the body. So benign is the type II diabetes that they do not come to the fore for year. By the time one gets diagnosed with the same the damage to the organs is already done. Therefore, the right step would to seek a diagnostic test In Delhi to get the right picture of what the

diabetes-physical-appearance

  • Unexplained weight loss: This is one of the common symptoms in type 1 diabetes, especially in women. With this type of diabetes, the body is unable to use all the calories that the food provides, even though the person follows a healthy diet. Due to this, the person loses weight, even without trying to do so.
  • Shunned growth: Kids who suffer from type 1 diabetes suffer from growth reduction. This should work as a red flag and prompt parents from taking the child to the doctor for a check-up.
  • Cracked skin: Uncontrolled high blood sugar can make one lose fluids at a faster rate and this could lead to dry and damaged skin especially in the feet and legs.
  • Foot problems: Some of the common foot problems that are faced include unhealed shoe bites, ulcers at feet.
  • Prickly skin: The skin can experience some kind of pricks along with needle damage as the diabetes also leads to nerve damage. This nerve damage can also alter a person’s sensitivity towards heat and cold.

Besides the aforementioned points and health problems, diabetes does not cause any major difference to the physical appearance.  However, it must be understood that diabetes is more challenging for women as compared to men. The reason being it can shun the growth of the baby if the women are pregnant. Hence, the earliest possible diagnosis followed by care is most essential. This can be done by keeping a regular track on diabetes and blood sugar level either by self-diagnosis or with the help of the labs which have the facilities and medical experts who can guide you through the entire. For more information in regards to the tests, you can communicate with the diagnostic labs in Delhi which are enlisted on the website of 3hcare, an online medical test planning portal wherein one can check for the availability of the tests and their costs as well.

The Importance Of Hygiene In Daily Life

It goes without saying that the good habits like maintaining hygiene must be cultivated on a daily basis to earn rich dividends of healthy life in the long run. With the world battling the dreaded coronavirus or COVID19, the need of hygiene has been underlined once again. It is therefore necessary to understand why hygiene is crucial to the prevention process which comes to play in countering most diseases and infections.

hygiene

First and foremost is the various health hazards which are widespread due to viral and bacterial infections. From an infected wound to not covering the body, to even not maintaining cleanliness of the basic kid, the human race is plagued with many diseases. These diseases are in direct relation to the hygiene habits which a person adopts. Keeping self sanitized as much as possible is of utmost importance for community, individual or groups. When in doubt about a disease which is caused due to lack of hygiene, be sure to visit the diagnostic labs in Delhi to get a test done. The test shall give a clear picture on what the source of the disease/illness is and the ways with which it can be countered.

One needs to know that the maintaining of hygiene itself can ward off many microbes causing illness. Therefore, one needs to ensure that they do the following on a daily basis:

  1. Bathe regularly- The entire body needs a wash given the fact that it gets sweaty and dirt smudged due to daily activities of different kind. Bathing not only washes off the germs in the body, it also keeps you refreshed and promotes healthy mental being.
  2. Washing hands- There is no complicated theory or practice involved in the washing of hands. And yet many of us fail to do it properly. Needless to say, the hands carry the vast majority of germs which further get transmitted to various organs of the body, the worst affected being the mouth. Therefore, one has to make it a point that they wash their hands with soap or use an alcohol based sanitizer gel to kill the germs instantly. Washing of hands is a must after visiting toilets, post coughing, sneezing, before and after consuming food.
  3. Clipping nails. Unclipped, long nails act as storehouse for the vicious bacteria and microorganisms and hence they need to be clipped at least once in a week. Finger nails should be kept short and should be washed frequently washed with water using soap.
  4. Oral hygiene- Oral hygiene must not be avoided as the oral health makes for an important cog in the personal hygiene. Good oral hygiene minimizes bacterial formation in the mouth, it is the direct reason for tooth and gum decay. It is highly you brush your teeth twice a day and floss your teeth before going to bed.

Once you inculcate such habits, the possibility of getting affected by disease due to low immunity power can also be negated in a significant manner.

Magnetic Resonance Imaging Under General Anesthesia

Today in medicine, one of the most effective methods for examining various internal organs of a patient is magnetic resonance imaging (MRI), which gives more than 90% of the correct diagnosis. This procedure is used and absolutely safe for adults and children from a very young age.

To obtain the best quality pictures, it is necessary that the child remains absolutely motionless during the procedure. Children are difficult to tolerate the need to lie still, especially young children, and the procedure can last from 20 to 90 minutes, depending on the location of the study and the individual anatomical and physical characteristics of the patient. In some cases, to ensure the necessary static, MRI under anesthesia is used.

Advantages and disadvantages of MRI under anesthesia

The MRI procedure under anesthesia has its advantages and disadvantages. The undoubted advantages include the complete immobility of the patient in a state of drug sleep, which allows a detailed and high-quality study. However, any drug anesthesia causes a state of discomfort, is an additional burden on the internal organs. Even the most modern drugs require patient supervision by a doctor for a certain time after the manipulation.

3h care pays special attention to providing optimal conditions for MRI examinations under anesthesia: all the necessary equipment is available, professional doctors work who various anesthesia techniques during MRI have done by MRI scan centre in Noida.

Introduction to medical sleep or sedation provides an opportunity to carry it out even in complex categories of patients. It is the anesthesia used during MRI that allows for complete diagnostics in both children and adults with almost no restrictions.

How is the procedure performed?

When performing an MRI under anesthesia, the following are used:

  • Inhalation techniques (mask, endotracheal);
  • Parenteral species (intravenous anaesthetics, intravenous analgesia with mechanical ventilation).

The procedure is performed in MRI test labs in Delhi in the presence of an anaesthetist who can use two options for patient sedation: superficial or deep. Drugs for anesthesia are administered intravenously, or sedation is performed by the inhalation method.

When is MRI necessary under general anesthesia?

MRI under anesthesia is performed for medical reasons or at the request of the patient.

It is used in the following situations:

  • With a tendency to panic attacks and fear of enclosed spaces (claustrophobia);
  • Children, starting from infancy and young children who cannot control their movements, or older children, if the child is panicky afraid of the procedure, and it is not possible to agree with him;
  • Patients with neurological disorders affecting motility (hyperkinesia, tremor, which cannot be eliminated with the help of other drugs);
  • With severe pain in the supine position (with damage to the nerve roots and trunks);
  • In the presence of mental illness in the patient, when it is not possible to expect the patient to adequately fulfil the request for a stationary stay in the tomography.

Where to do an MRI under sedation

When choosing a location for the diagnosis should take into account the characteristics of the patient. So, to study the body of a child, you must contact a specialized paediatric institution.

Prices for this procedure may vary. Practice shows that the results obtained in different clinics will also vary. When choosing a medical centre, it is necessary to focus on the availability of modern high-quality equipment - the more its capacity, the more reliable the result will be.

It is important that the medical centre has an appropriate certificate for such studies. The feedback from our patients is positive. Those who have passed the procedure note the importance of choosing qualified specialists and observing the rules for preparing for the procedure.

Myths And Realities Of Ultrasound, In Pregnancy

First of all, it is very important to understand the way an ultrasound device works.

The ultrasound uses sound waves, which penetrate the tissues of the body, by placing the transducer accompanied by gel as a conductive medium and in this way the sound waves that bounce off the different organs are processed by the ultrasound devices in two-dimensional images.

ultrasound-in-pregnancy

These images will give the doctor information about the size, shape, and texture of the body part, also in the case of pregnancy determine the condition of the baby, listen to his heart, see his movements and if possible observe the sex.

The images are interpreted by radiologists and sonographers, who will inform the patient about the different findings and make the study diagnosis.

An ultrasound scan usually takes 25-30 minutes, but it may take a little longer.

Many people say that ultrasound can cause diseases in the baby, that you don't have to do many because they hurt you and this causes fear and insecurity in your breast. However, Pregnancy Ultrasound can give you and your doctor valuable information about the status of your baby and its correct development.

Since we understood how ultrasound equipment works let's get into the subject of myths and realities.

- MYTH THE ULTRASOUND CAN DAMAGE THE BABY.

* REALITY ultrasound in a simple innocuous and painless technique. It does not involve radiation or exposure, for which it is safe for both the breast and the baby.

-MYTH: NO MORE THAN THREE ULTRASOUNDS MUST BE MADE.

* REALITY: It really depends a lot on the indication of your doctor, and it would have no risk to perform more ultrasounds, you have to keep in mind that the baby's development is constant and that there are risks and complications; such as multiple pregnancies, hypertension (high pressure in the mother), stunted baby growth, gestational diabetes, and bleeding.

- MYTH: THE ULTRASOUND OF THE FIRST QUARTER MUST BE TRANSVAGINAL.

* FACT: Although it is the favourite method by radiologists and sonographers before 12 weeks of pregnancy because it allows a sharper image, abdominal ultrasound can be done without any problem and as an example is the image taken in a baby of only 10 weeks of life.

- MYTH: 4D ULTRASOUND IS BETTER THAN NORMAL (2D).

* REALITY: this is false, most of the diagnoses that are made by ultrasound are made by means of 2D ultrasound or normal call, however, 4d ultrasound in Delhi allows us to see in three dimensions and in addition to the movements in real-time to babies, which allows us to see your body and face.

- MYTH: 4D ULTRASOUND CAN ONLY BE DONE AT THE END OF PREGNANCY.

* FACT: Ultrasound of this type is recommended between weeks 26 and 30 because the baby has the size to assess small details such as the mouth, nose, and fingers are his hands, but if they can be done when the babies are small.

- MYTH: THE ECOGRAPHY DETECTS THE BABY'S ANOMALIES.

* REALITY: true, although only in one part. Ultrasound is a diagnostic tool dependent on the ability and knowledge that the doctor has when conducting the study, this being very important, as well as the quality and resolution of the ultrasound equipment. There are studies that show that the ability to detect anomalies at close to 75%, which means that almost one in every 4 anomalies could go unnoticed.

General Knowledge About MRI Test Scan

In the simplest way, it is possible to describe Magnetic Resonance, MR, as the technique of creating images through radiofrequency waves in a strong magnetic field environment. Being a radiation-free technique, MRI is also used for imaging soft tissues.

mri-test-scan

How is it applied?

During the MR examination, the patient needs to lie in a prone tube, in a prone position, without any movement. Since this tube is large, it does not usually cause discomfort. People with a fear of confined space can be given a mild sedative before shooting.

Before the examination, a thin catheter is inserted into the patient's arm vein, and a drug called contrast material, which is unlikely to be allergic, is injected through this catheter during shooting. Contrast agents used in MR examinations can be used except for people with kidney failure. Breast MR Shots can take 30-60 minutes. It is important to first know the MRI test cost in Noida.

What Should Be Considered?

Other examinations may also be needed: MRI examination of the breast can provide valuable information that cannot be obtained by other imaging methods. However, it still does not replace mammography or ultrasonography. All reviews provide different information and all findings need to be evaluated together.

In Which Cases Is It Recommended?

  • To determine whether there is more than one cancer focus in the breast before surgery in patients who have breast cancer and breast-sparing treatment is planned.
  • To understand whether cancer has spread to the chest wall and the opposite breast in patients with breast cancer
  • In women who have been treated for breast cancer due to breast cancer, changes in the breast related to surgery can be distinguished from recurrent cancer.
  • In the elucidation of any suspicious situation detected in mammography, ultrasonography or manual examination
  • In the evaluation of the success of chemotherapy in patients with advanced breast cancer
  • For screening purposes, in determining whether high-risk women have breast cancer
  • In determining the main cancer focus in patients with metastatic cancer.
  • In determining whether there is any damage to the prosthesis in women with silicone prosthesis and evaluating the suspicious findings in the breast.
  • Who Is Not Recommended?
  • For those who have metallic objects on their body
  • Those with severe kidney failure
  • Those who are allergic to MR contrast agents
  • For those who cannot lie still for a long time
  • To overweight people

According to other breast imaging methods;

  1. More information can be obtained. In this way, many cancer foci, which cannot be shown by other methods, can be detected. However, MR is not seen alone in detecting breast cancer.
  2. Intense breasts, treated breasts, silicone prosthetic breasts, which are difficult to evaluate in mammography, can be examined.
  3. With MRI, especially in high-risk women, screening results can be obtained according to mammography and ultrasonography.
  4. Breast cancers and very specific breast cancers cannot be detected by MR. Therefore, it should always be evaluated in conjunction with other imaging methods and clinical examination findings.

According to other imaging methods;

  • Suspicious findings can be detected in MR in benign diseases of the breast. Therefore, unnecessary biopsy or surgery may be required.
  • Breast cancers and very specific breast cancers cannot be detected by MR. Therefore, it should always be evaluated in conjunction with other imaging methods and clinical examination findings.
  • If suspicious findings that can only be visualized with MRI are detected, the biopsy should be performed under MR guidance.

Successful results are obtained especially with the imaging of soft tissues with MRI done by MRI scan centres in east Delhi. Many cancer foci that cannot be detected by other diagnostic methods can be detected. However, MR is not seen alone in detecting breast cancer.

Common Queries About Ultrasound

Here is a list of most common questions one should want to ask before undergoing an ultrasound test:

1- Can ultrasound harm the baby?

Ultrasound uses high-frequency sound waves that help us generate medical images; As such, sound waves interact with the tissue producing movements at the cellular level and this is how they travel through the body. The ultrasound as such is harmless and does not generate any type of ionizing radiation as with x-rays or tomography.

ultrasound-question

2- Can perform many ultrasounds during pregnancy cause reflux?

There is nothing that relates to reflux to ultrasound. Reflux is related to the maturation of the gastroesophageal system, specifically with the proper functioning of the oesophageal sphincter that connects the oesophagus with the stomach. This sphincter or valve prevents gastric juices from returning to the oesophagus, which is not prepared to withstand the acidity of gastric juices.

This situation of "returning milk" It is relatively common and should stop happening one year after the baby's life; In any case, it is always advisable to visit the doctor to rule out that these types of conditions respond to something else.

3- Do ultrasound use radiation?

No, ultrasound does not use any type of radiation. Ultrasound uses high-frequency sound that is inaudible to humans. Humans listen in an acoustic frequency range of 20 to 20,000 Hertz. The ultrasound uses above 1 Megahertz that is 1,000,000 Hertz. The sound frequency above 1 Megahertz is not audible to humans or to most animals.

4- How long do the results of an ultrasound take?

This depends on the doctor doing the study. There is no rule about it. There are doctors who generate the report immediately after doing the study; or doctors who prefer to wait and make the report later to analyse the study in much more detail.

5- Do 3-D ultrasound use stronger waves than 2-D ultrasound?

No, it's the same ultrasound, just change the way the transducer works. The 3D / 4D transducer is essentially the same as that of 2D but is connected to a motor that moves it to be able to make volumetric acquisitions. Everything else is image processing in ultrasound equipment.

It is said easy but in reality, it requires a high processing capacity of the equipment to obtain good quality 3D or 4D images. It should be remembered that 3D or 4D not only serves to see the face of the BB, currently, volumetry is an advanced diagnostic tool for medical specialists, which allows them to assess in more detail the brain, heart, abdomen, limbs, and evaluation of blood flows, especially if a pathology is suspected.

7- With a 3D ultrasound is the prediction of the baby's sex easier and safer?

Not really, 3D ultrasound helps patients understand sex more easily. Volumetric ultrasound always depends on the foetus and its position.

8- Can a vaginal ultrasound harm the baby or hurt the mother?

No, pregnancy ultrasound does not harm the baby or the mother. The resolution of this application is advisable to make timely diagnoses during the first trimester, which will always be higher than the suprapubic ultrasound.
