Cardiac PET Scan Q & A

What is a cardiac PET scan?

A positron emission tomography (PET) scan is a noninvasive heart imaging test. It’s a type of nuclear imaging, which means a PET scan detects radiation to create pictures of your heart. 

When might I need a cardiac PET scan?

A cardiac PET scan may detect heart problems early, before other imaging tests can do so. PET scans can accurately diagnose coronary artery disease and can also pinpoint areas where you have low blood flow in your heart. 

In addition, cardiac PET scans can determine what parts of your heart are still working and which parts are nonfunctional. So, you may need this scan to determine whether you’d benefit from percutaneous coronary intervention (PCI) like angioplasty and stenting or coronary artery bypass surgery. 

How does a cardiac PET scan work?

In a cardiac PET scan, your Capitol Cardiology Associates provider injects a tracer (the radioactive material) into your bloodstream. The tracers used for a PET scan are primarily natural bodily compounds like water, glucose, and ammonia with a tiny amount of radioactive material added. 

Once inside your body, the tracer emits a gamma ray, a type of energy. A gamma detector then recognizes those gamma rays and uses them to create detailed pictures of your heart. A cardiac PET scan includes images from many different directions to create a comprehensive view of your heart. 

Your doctor analyzes the images to find the tracer. The way your heart absorbs and uses the tracer reveals how well the heart’s functioning. Your doctor evaluates the different parts of your heart in detail to determine what heart problems you have and what kind of treatment you might need. 

Are cardiac PET scans safe?

Cardiac PET scans are safe for most patients because they use only a small amount of radiation. Your body flushes the radiation out through your kidneys quite rapidly. 

How do I get ready for a cardiac PET scan?

Capitol Cardiology Associates provides complete instructions for you ahead of time. You’ll need to fast for four to six hours before your cardiac PET scan. You may need to avoid caffeine for a full 24 hours ahead of the test. 

Your provider discusses all your medications with you before the cardiac PET scan. You may need to skip a dose of some medications before the procedure.
