Abdominal CT And Diseases In Which It Is Necessary

In the diagnosis of abdominal ailments for which no explanation is found with the most common medical tests, there is the possibility of performing an abdominal CT scan, which offers images that allow diseases of the digestive system and other internal organs of this part of the body to be detected.

What is an abdominal CT?

CT or computed tomography is a diagnostic test that uses x-rays to obtain images of the inside of the organism in the form of transverse cuts or, also, in the form of three-dimensional images.

Abdominal CT is especially suitable for determining the cause of pain in this area. Many of the structures of the abdomen contain air and cannot be seen well with other types of tests, such as abdominal echoes. It is then that abdominal CT is the best alternative to obtain a view of the abdomen, with the use of contrast, a liquid substance that can be given to the patient to drink or injected.

Characteristics of abdominal CT as a diagnostic test

Among the main features of CT Scan Abdomen, they highlight that it is a rapid and painless diagnostic test. It is nothing invasive, and its accuracy is better than other imaging tests.

CT images of the internal organs of the abdomen, as well as those of the bones, soft tissues, and blood vessels, have greater detail than those generated by radiographs, especially in the observation of soft tissues and blood vessels.

In addition, the technology that uses this type of apparatus allows the transverse images generated during the CT scan can be observed in multiple planes or even create three-dimensional images with them.

What is abdominal CT used for?

Due to its characteristics, it could be said that abdominal CT is a diagnostic test that serves to explain diseases that have not been able to be compared with other tests.

It is often used to determine the origin of an abdominal pain for which no explanation is found, and in emergencies, it can identify injuries and internal hemorrhages quickly enough to help save lives.

It is also effective for the diagnosis and treatment of urological conditions, in the observation of patients who have been operated and in the monitoring of oncological processes.

Diseases in which abdominal CT is useful

Specifically, abdominal CT is used to diagnose the reason of having abdominal or pelvic pain, and for the detection and monitoring of diseases of the internal organs, the small intestine and the colon.

It is used to detect infections, such as appendicitis or accumulations of infected fluid (abscesses), and can help detect stones in the kidneys and bladder.

Abdominal CT scans are also used in the diagnosis of inflammatory bowel diseases (Crohn's disease, pancreatitis, liver cirrhosis, etc.) and are used in the evaluation and treatment of various tumors, such as liver, kidney, pancreas, cancer of ovaries and bladder, as well as lymphoma.

If you are waiting for this test and do not want to wait any longer, from our medical services website, we can manage your performance, with the appropriate medical advice and a network of more than 5,000 private centers arranged. It is good to know CT scan abdomen cost in Delhi before going to have one.

Diagnostic Imaging Of The Chest – Lung Scan

The diagnostic imaging of the chest includes radiography, computed tomography (CT), magnetic resonance imaging (MRI), scintigraphy, ultrasound, and positron emission tomography (PET). Radiography is almost always performed. Other imaging tests are carried out as necessary to obtain specific information for the purpose of formulating the diagnosis.

The chest X-ray

It is performed routinely from the back to the front. In general, an image of the lateral section is also acquired. Chest X-rays provide a good definition of the profile of the heart and large blood vessels and can usually reveal a serious disease of the lungs, pleural cavities, or rib cage, including the ribs. For example, chest radiographs may show pneumonia, some lung cancers, chronic obstructive pulmonary disease, lung collapse (atelectasis), and the passage of air (pneumothorax) or fluid (pleural effusion) in the pleural cavity. Although thoracic radiographs rarely provide sufficient information to determine the exact cause of these abnormalities.

A computed tomography (CT) of the chest provides more detail than a simple radiograph. With the CT, a series of radiological images is analyzed with a computer, which, subsequently, provides multiple projections on different planes, such as longitudinal and transverse sections. Before having a CT scan it is good to know CT scan cost in Delhi NCR. During CT, a visible X-ray substance (called a radiopaque contrast agent) can be injected into the bloodstream or administered orally to establish the nature of certain abnormalities in the chest. High-resolution CT and spiral CT are more specialized CT procedures. High-resolution CT can reveal further details in relation to lung diseases. Spiral CT can produce three-dimensional images.

It includes the injection of a radiopaque contrast medium into a vein in the arm to create images of blood vessels, along with the artery that carries blood from the heart to the lungs (pulmonary artery). Currently, angiography is used instead of scintigraphy to diagnose the presence of blood clots in the pulmonary artery (pulmonary embolism).

Even the magnetic resonance imaging (MRI) provides very detailed images, which are especially useful in the case of vascular changes suspect in the chest, such as an aortic aneurysm. However, the MRI takes longer and has higher costs than the TC. Furthermore, the MRI resolution is lower than that of CT for the diagnosis of abnormalities in the lungs, and therefore this examination is not frequently used in the field of diagnostic imaging. The cost of CT scan in Delhi vary according to the place it is going to be held. Unlike CT, MRI does not use radiation.

The lung scan may be useful to detect the presence of blood clots in the lungs (pulmonary emboli); however, in the diagnostic process of this disease, it has been largely replaced by ' CT angiography. Scintigraphy can also be used during the preoperative evaluation of patients with lung cancer. Pulmonary scintigraphy uses modest amounts of short-lived radioactive material to define the flow of air and blood through the lungs. Usually, the test is performed in two phases.

In the first phase (perfusional lung scan), a radioactive substance is injected into a vein, and a scanner reproduces an image of the mode of distribution through the pulmonary vessels. If the perfusion ultrasonography is altered, a second phase (pulmonary ventilation ultrasound) is required; the patient inhales a radioactive gas, and the apparatus produces an image of the distributive pattern through the lungs.

Is It Possible To Do CT And MRI For Children?

Imagine that a doctor prescribes your child to undergo a computed tomography or magnetic resonance imaging. Most likely, you are, first of all, thinking about the possible risks: will this or that research harm the children's organism? How will the child take them?

Is there a danger?

Magnetic resonance imaging (MRI) is an absolutely safe method of research, since it does not use ionizing radiation sources. There is no reason to worry about the hypothetical harm to the child from this type of diagnosis. When conducting computed tomography (CT), X-rays are used, so the concerns of the parents are well founded. But in the medical organizations of the Moscow Department of Health, special pediatric research protocols are used, which allow reducing the radiation dose to the minimum harmless values. Therefore, this procedure does not have any negative impact.

Is it possible to replace a CT scan with a safer MRI?

MRI and CT are two different methods of radiation diagnosis, which are not always interchangeable. They give different information about the state of health, so the question of what kind of research to conduct a child is decided directly by the attending physician or radiologist. The greatest harm to health is caused not by a microdose of X-rays, but by insufficient diagnostics.

Is it necessary to give children anesthesia during CT and MRI?

During CT and especially MRI, it is very important that the child remains stationary throughout the procedure; otherwise, the results will not be accurate or not suitable for analysis. The MRI procedure takes an average of 20-30 minutes, which means that the child will have to lie motionless all this time. As practice shows, children 5-6 years and older do an excellent job with this task. But earlier patients are difficult to maintain immobility.

For children under 3 years old, CT and MRI are performed only in a hospital, under the supervision of specialists. Before the study, the child is given a sedative or mild inhalation anesthesia, after which he wakes up quickly and easily.

CT and MRI with contrast enhancement

To diagnose some diseases, a child may need to have a CT scan or MRI with a so-called contrast - and you should not be afraid of this study. Before the procedure, the doctor will carefully collect anamnesis and find out all about possible contraindications. For greater safety, a study with contrast enhancement in children is carried out only in hospitals.

Where will my child be taken for CT and MRI?

According to the order of the Moscow Department of Health, the routing of children on CT and MRI in hospitals is carried out in accordance with the assignment by the district. That is, depending on the CT scan centre in which you are monitored, you will be assigned a referral to one or another institution.

In most cases, children under 3 years old are sent to inpatient medical organizations for CT and MRI. This is due to the need to introduce anesthesia for the success of the study. Children over 4 years old can undergo an outpatient study.

Cancer and PET CT Scan

Everyone who has suffered from cancer knows the importance of early diagnosis and effective treatment. However, the situation in the country is absurd: there is not enough money for medicine, and modern treatment with effective medicines is paid for by the patient or depends on the availability of public donations, therefore high-tech diagnostics are mostly available in private medical institutions.

PET / CT allows you to assess the extent of the tumor lesion of the patient and correctly determine the stage of the disease. Information on how far malignant cells have spread is extremely important for the choice of treatment tactics. Examination of patients undergoing radiotherapy and chemotherapy, or undergoing surgery, is necessary to monitor the results of prescribed treatment - PET / CT scan will show how the tumor changes, will allow to see new foci and relapses.

A full-body PET / CT scan is performed for:

  • Detection of metastases and primary tumor foci;
  • Determine the extent of the tumor process;
  • Evaluation of the effectiveness of treatment;
  • Differentiation of benign and malignant tumors;
  • Planning tactics of therapy.

In PET-Technology, diagnostics with 18-FDG is carried out for the following diseases: malignant skeletal tumors, melanoma, Hodgkin's disease and non-Hodgkin's lymphomas, soft tissue sarcomas, thyroid cancer, breast, cervix, thymus, testicles, lung glands, ovaries, stomach and intestines.

The test scan takes place in two stages:

The introduction of the drug. The patient is given an intravenous injection. The procedure is painless, sometimes accompanied by a sensation of heat. The drug is distributed in all cells within an hour. Important: After the introduction of the drug you need to lie quietly, do not move, do not talk, do not read - 18-FDG accumulates in actively working muscles, which can affect the results. Drink clean water to improve cell imaging.

PET/CT scan. The patient is placed in a tomograph, where a computed tomography of the whole body is first performed, followed by a positron emission tomography of the whole body. In some cases, a contrast agent is additionally introduced, which improves the visualization of the hollow organs - the intestines and vessels. The software of the device superimposes CT scans on PET scans, as a result, structural, physiological and metabolic changes in the tissues can be assessed.

PET / CT does not last more than an hour, but in the center you will spend from 2 to 5 hours - this includes preliminary preparation, documentation, and rest after the procedure. Before the examination, you need to change into comfortable clothes and remove all products containing metal.

During the rest period it is important to maintain immobility, this contributes to the correct distribution of the radiopharmaceutical and, as a result, to a qualitative display of the pathological focus. To obtain a good quality of the study, it is necessary to remain stationary during the entire scan time (the study can last from 20 to 40 minutes).

After completing the procedures, do not leave the territory of the diagnostic lab in Delhi without the permission of the medical staff, as it may sometimes be necessary to repeat the scan.

What Must Be Kept In Mind About Pregnancy Tests?

Pregnancy tests are no more a taboo or something which cannot be done at home as well. With the advancement in the field of medical science, their pregnancy kits which add to the swiftness. They are handy and do not cost you a fortune. When in doubt, they can be used anytime without the consultation of an expert. But it must also be taken into note that all pregnancy test kits, the expensive ones, in particular, does not equate to being accurate. Hence, we discuss some of the key factors which must be kept in mind about pregnancy tests:

  1. Take a sample of the first-morning urine- By using urine from the first thing in the morning you actually have more of the hormone (hCG) that the test is looking for building up in your urine. It can thus be beneficial for getting an accurate test reading. All you need is keep your forgetfulness aside and do not take a leak. Many also are of the opinion that if you hold up urine for more than four hours, it is going to be as useful as the first-morning urine as a sample to check whether you are pregnant or not. But the key is basically to not overload yourself on fluids to make your urine more dilute.
  2. Read the instructions carefully- Anxiety kicks in at the very thought of checking for pregnancy pretty much like going for the first ct scan. It has certainly the potential to change our lives forever. Nevertheless, one needs to be patient and But, before you even enter the bathroom, pull out the instructions and read them thoroughly. Leave nothing to chance and if you have had a test previously, don't rely upon them completely. Also, there are limits which decide on how long the test is valid to read.
  3. Follow up on the tests- If you received a negative result which was not of the expected kind, or you have not started your period a week later, you need to retest. It is very much a process that most of the pregnancy tests ask you to follow. The reason being that it allows the body to produce detectable amounts of hCG in your urine. Thus it can be construed that a negative test may not always be a negative test. Perhaps, it would be too early for the test to turn positive.

Pregnancy can be sensitive as well as a volatile issue for many women trying to avoid unwanted pregnancy. It is not just the unmarried women but also the married ones planning a family who go for these tests all by themselves. That being said, it is most advised to seek medical help of the expert if there are too many contradictions on results. The test kits are made to give the women a firsthand insight on how accurate their conjecture about the pregnancy is. When in doubt, it is always better to take a step ahead.

What is the Best Method to Detect Colorectal Cancer as Soon as Possible?

Patients with certain diseases or predisposing conditions can benefit from a surveillance program: early diagnosis or screening. It consists of performing a fecal occult blood test and a colonoscopy to diagnose the tumor at an early or early stage in people who do not have any symptoms and have certain risk factors.

The diagnostic process begins with a proper interrogation, in which the doctor will collect information about personal and family medical history, and a complete physical examination of all systems. The information obtained in both processes will help direct the type of complementary examinations that must be performed to complete the diagnosis.

Today we have a wide range of diagnostic methods or complementary tests aimed at diagnosing cancer:

Analytical: the hemogram can show if there is anemia, this being an indirect sign of bleeding. The blood biochemistry can guide on the function of organs like the liver or the kidney.

Stool test: This is a test to detect blood in the stool, which may indicate the presence of polyps or cancer.

Tumor markers: Tumor markers are substances that can often be discovered in higher than normal amounts in the blood, urine, or body tissues of some patients with certain types of cancer. It is important to consider that tumor markers can be normal in a patient with cancer and that not all tumors can produce an elevation of markers.

Colonoscopy: colonoscopy is the introduction of a device that has a light at the end and that allows to visualize the inside of the colon and rectum and take a biopsy if the observed lesions are required. With this technique, polyps can also be resected if they are not very large.

Radiological examinations:

Opaque enema: consists in the administration of a barium contrast for the year. This contrast shows the silhouette of color and straight. It can detect injuries of a certain size. If a complete colonoscopy has been performed, it is not necessary to perform an opaque enema.

Abdominal or abdominal-pelvic ultrasound: based on whole abdomen ultrasound price. It is useful to study the liver, to know if there is free fluid in the abdomen or to detect masses in the abdomen or pelvis.

Scanning (CT scan cost in Delhi NCR) of the thorax and abdomen: it provides information on local extension, if there are metastases in the liver, lung, etc.

Abdominal resonance: it is a technique different from CT, which is usually done when there are findings in the scanner that require complementary examinations. It is essential for the correct staging of rectal cancer.

Endoscopic ultrasound: it combines the endoscopic technique with an ultrasound transmitter and produces an image (ultrasound). It is very useful for the preoperative diagnosis of rectal cancer.

Positron emission tomography (PET CT scan): is a nuclear medicine test, which involves injecting a marked contrast with a radioactive substance and measuring the emission of particles called positrons giving a global view of the body and showing if there is disease.

Laparoscopy: is a technique that involves inserting an endoscope into the abdominal cavity, through holes that the surgeon makes in the abdominal wall. In rare cases this maneuver is reached for the sole purpose of establishing the diagnosis. It is usually used as a surgical technique to remove certain tumors in this area.
