What is a PET Exam?

Cardiac Positron Emission Tomography (PET) exams help to evaluate heart health by measuring the blood flow brought by the coronary arteries to the heart muscle. This scan lets doctors see inside your body. A PET scan is different from an MRI or a CT scan, because it shows how your organs and systems are working. For decades, doctors have used cardiac PET scans to safely and accurately identify the presence or absence of coronary artery disease in people who have had symptoms and/or risk factors. Exam results can also indicate if any follow-up treatment is needed.
