Exercise Cardiac Perfusion Study
An exercise cardiac perfusion study checks the blood flow to your heart. This test measures your heart’s response to exercise and can detect coronary artery disease (CAD). It can also show the severity of any blockages.
The test is made up of two sets of scans. The first scan is taken when you're at rest. The second scan is done after you walk on a treadmill or pedal a stationary bike. Both scans use a small amount of radioactive tracers to show your blood flow (perfusion) to the heart muscle. The amount of radiation used is small and well within limits that aren't harmful. The total test time is about three-and-a-half hours.
