PET and the Heart
What is PET?
A cardiac PET scan is a type of stress test in which blood flow to the heart muscle is visualized with a radiotracer and a special scanner. PET provides an accurate non-invasive assessment of the coronary arteries. Pictures of the myocardial blood flow are taken before and after pharmacologic stress instead of exercise to determine if maximum blood flow is restricted by narrowing of the coronary arteries.
