Nuclear Stress Test (MPI)
A Nuclear Stress Test, also known as Myocardial Perfusion Imaging (MPI), is done to determine how well the coronary arteries are delivering blood to your heart, as well as areas of the heart muscle that aren’t getting enough blood flow.
If the test shows a lack of blood flow during exercise or stress, but is normal at rest, it could mean that an artery that carries blood to your heart is narrowed or blocked. If the test shows a lack of blood flow to a portion of the heart muscle during exercise or stress and at rest, it could mean that your heart muscle is scarred, possibly from a past heart attack.
MPI is useful in patients with chest discomfort to see if the discomfort comes from a 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 it can tell your doctor with good certainty if any heart arteries are blocked and how many.
