PET Cardiac scans- Its inevitability

A PET scan of the heart is a non-invasive nuclear imaging test. It utilizes radioactive tracers to create photos of your heart. Specialists utilize cardiovascular PET sweeps to analyze coronary diseases and other heart related ailments.

Reasons to go for PET Cardiac scans:

If there are any artery coronary issues or if the blood flow is low in heart, a PET Cardiac scan is a must. This scan can also help to find out if there are injured or damaged tissues. If the tissues are alive and functioning, a coronary artery bypass surgery can help.

Process of PET scan:

You will be injected a radioactive tracer into the blood. A small amount of radioactive material will be used that will not affect you. This material will produce the gamma rays in your body. These rays are identified by gamma detectors and they help to capture the images from your body. The thin slice images of your heart from different angles will be captured. The doctor will then let you know if your heart muscle is dead, alive, functioning or need medication.

PET Scan for Myocardial Viability:

In Myocardial viability the heart muscle contracts and helps the left ventricle to pump blood throughout the body. You will be asked to carry out a myocardial viability test to find out the myocardial glucose level. FDG will be used by the team of doctors.

Things to consider before the test:

Avoid drink any chocolate or caffeine related products.

If you are non-diabetic, you should refrain from eating 6 hours prior to the test. You can take water.

Do not take any medicine before the test.

Wear loose clothes.

Remove all the jewelery before you appear for the test.

Things to consider during the test:

You must be prepared to spend 3-4 hours for the scan.

An intravenous injection considering of radioactive material will be given to you. The dose of radioactivity will be low and there wouldn’t be any side-effects.

You will be made to wait for an hour before taking the scan.

A nuclear medicine scanner will be used to get the picture of the images.

Sarcoidosis:

Sarcoidosis is an inflammatory disease where one can find out the granulomas in affected organs. The organs are skin, liver, kidney, spleen, eyes, kidneys and central nervous system. Earlier, FDG-PET/CT studies have proved that inflammatory cardiac Sarcoidosis might lead to an instant heart failure or cardiac arrest. The clinical specialist says that it is very difficult to diagnose cardiac Sarcoidosis.

If you have any cardiac issues, do not hesitate to visit the doctor. The doctor will recommend the necessary tests to be carried out and do follow the instructions!
