Why is STRESS MYOCARDIAL PERFUSION SCAN ?

Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through (perfuses) your heart muscle. It can show areas of the heart muscle that aren’t getting enough blood flow. This test is often called a nuclear stress test. It can also show how well the heart muscle is pumping. MPI is useful in patients with chest discomfort to see if the discomfort comes from lack of blood flow to the heart muscle caused by narrowed or blocked heart arteries (angina). Myocardial perfusion imaging doesn’t show the heart arteries themselves but can tell your doctor with good certainty if any heart arteries are blocked and how many. MPI can also show if you’ve previously had a heart attack.
