Nuclear Medicine Procedure in India

What is nuclear medicine?

Nuclear medicine may be a specialized area of radiology that uses very small amounts of radioactive materials, or radiopharmaceuticals, to look at organ function and structure. medicine imaging may be a combination of the many different disciplines. These include chemistry, physics, mathematics, technology, and medicine. This branch of radiology is usually wont to help diagnose and treat abnormalities very early within the progression of a disease, like thyroid cancer.

Because X-rays undergo soft tissue, like intestines, muscles, and blood vessels, these tissues are difficult to see on a typical X-ray, unless a contrast agent is employed. this enables the tissue to be seen more clearly. Nuclear imaging enables visualization of organ and tissue structure also as function. The extent to which a radiopharmaceutical is absorbed, or "taken up," by a specific organ or tissue may indicate the extent of the function of the organ or tissue being studied. Thus, diagnostic X-rays are used primarily to review anatomy. Nuclear imaging is employed to review organ and tissue function.

A tiny amount of a radioactive substance is employed during the procedure to help within the exam. Several differing types of radionuclides are available. These include sorts of weather technetium, thallium, gallium, iodine, and xenon. the sort of radionuclide used will depend upon the sort of study and therefore the part being studied.

After the radionuclide has been given and has collected within the body tissue under study, radiation is going to be given off. This radiation is detected by a radiation detector. the foremost common sort of detector is that the gamma camera.

During a nuclear scan, the healthcare provider can assess and diagnose various conditions, like tumors, infections, hematomas, organ enlargement, or cysts with the help of measuring the behavior of the radionuclide within the body. A nuclear scan can also be wont to assess organ function and blood circulation.

In planar imaging, the gamma camera remains stationary. The resulting images are two-dimensional (2D). Single-photon emission computerized tomography, or SPECT, produces axial "slices" of the organ in question because the gamma camera rotates around the patient. These slices are almost like those performed by a CT scan. In certain instances, like PET scans, three-dimensional (3D) images are often performed using the SPECT data.

Scans are wont to diagnose many medical conditions and diseases. a number of the more common tests include the following:

Renal scans. These are wont to examine the kidneys and to seek out any abnormalities. These include abnormal function or obstruction of the renal blood flow.

Thyroid scans. These are wont to evaluate thyroid function or to raised evaluate a thyroid nodule or mass.

Bone scans. These are wont to evaluate any degenerative and/or arthritic changes within the joints, to seek out bone diseases and tumors, and/or to work out the explanation for bone pain or inflammation.

Gallium scans. These are wont to diagnose active infectious and/or inflammatory diseases, tumors, and abscesses.

Heart scans. These are wont to identify abnormal blood flow to the guts, to work out the extent of the damage of the guts muscle after an attack, and/or to live heart function.

Brain scans. These are wont to investigate problems within the brain and/or within the blood circulation to the brain.

Breast scans. These are often utilized in conjunction with mammograms to locate cancerous tissue within the breast.

How are medicine scans done?
As stated above, medicine scans could also be performed on many organs and tissues of the body. Each sort of scan employs certain technology, radionuclides, and procedures.

A medicine scan consists of three phases: tracer (radionuclide) administration, taking images, and image interpretation. the quantity of your time between administration of the tracer and therefore the taking of the pictures may range from a couple of moments to a couple of days. The time depends on the body tissue being examined and therefore the tracer getting used. Some scans are completed in minutes, while others may have the patient to return a couple of times over the course of several days.

One of the foremost commonly performed medicine exams maybe a heart scan. Myocardial perfusion scans and radionuclide angiography scans are the two primary heart scans. so as to offer an example of how medicine scans are done, the method for a resting radionuclide angiogram (RNA) scan is presented below.

Although each facility may have specific protocols in situ, generally, a resting RNA follows this process:

The patient is going to be asked to get rid of any jewelry or other objects which will interfere with the procedure.

If the patient is asked to get rid of clothing, he or she is going to tend a gown to wear.

An intravenous (IV) line is going to be started within the hand or arm.

The patient is going to be connected to an electrocardiogram (ECG) machine with electrodes (leads) and a vital sign cuff is going to be attached to the arm.
The patient will lie flat on a table within the procedure room.
The radionuclide is going to be injected into the vein to "tag" the red blood cells. Alternatively, a little amount of blood is going to be withdrawn from the vein in order that it are often tagged with the radionuclide. The radionuclide is going to be added to the blood and can be absorbed into the red blood cells.

After the tagging procedure, the blood is going to be returned into the vein through the IV tube. The progress of the tagged red blood cells through the guts are going to be traced with a scanner.
During the procedure, it'll be vital to lie as still as possible. Any movement can adversely affect the standard of the scan.
The gamma camera is going to be positioned over the patient as he or she lies on the table, and can obtain images of the guts because it pumps the blood through the body.
The patient could also be asked to various positions during the test. However, once the position has been changed, the patient will be got to lie still without talking.
After the scan is complete, the IV line is going to be discontinued. The patient is going to be allowed to go away unless the healthcare provider gives different instructions.

Safety Concerns
 As with any radiologic procedure, pregnant women should consult their physician before undergoing a medical exam. Generally, medicine scans aren't performed on pregnant women. Patients should also confirm their physician knows what medications they're taking and if they're a nursing mother before undergoing a medical exam.
What is medicine A typical medicine imaging procedure:
The radiotracers accumulate within the organ or area which can be examined.
 A special camera or imaging device which will read radioactive emissions is then ready to take images of the world, creating pictures and molecular information that physicians can use to form a diagnosis.
 In some medical centers, the pictures from medical imaging are often utilized in conjunction with the results of CT or MRI scans during a process referred to as ‘image fusion’. Image fusion allows for more precise information for a diagnosis. Scans are noninvasive procedures. apart from a pinprick, you'll feel from an injection, they're also painless.
Once the radioisotope has accumulated within the region of the body under study, the technologist positions a camera on the brink of the region and begins the scanning process. How to steel oneself against a medicine exam varies because each study is different. Patients are urged to consult their own physician for specific instructions about the way to steel oneself against their specific procedure.
