Nuclear Positron Emission Tomography (PET) Stress Test

The nuclear positron emission tomography (PET) stress test evaluates the blood supply to your heart muscle during periods of exercise (stress) and rest.

This test helps doctors determine if you have a blockage in one or more arteries of the heart. The arteries that supply blood to the heart muscle can become clogged or narrowed from the buildup of plaque (called atherosclerosis or coronary artery disease). We use safe, radioactive tracers to examine your heart’s blood flow. Images of the tracer allow us to see the heart muscle receiving the blood supply more clearly.
