Myocardial Perfusion Imaging
Myocardial perfusion imaging is a test to look at the blood flow and function of the heart. It uses a low dose of a radioactive agent. Blood flow to the heart is best tested when your heart is working hard, so this test is usually done during exercise. If you cannot exercise, your doctor may use a drug to increase your heart's workload.

Myocardial perfusion imaging is used to look for any damage to your heart. It may also help to determine your future risk of heart damage.
Your doctor may recommend the test to:
- Determine if you are at risk for a heart attack
- See if you need coronary angiography, angioplasty, or heart surgery
- See which areas of the heart muscle have poor blood supply
- Provide information about the heart’s pumping ability
- See the amount of scarring that occurred from a heart attack
- Check the success of angioplasty or coronary bypass surgery
