Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through your heart muscle. It can show areas of the heart muscle that aren’t getting enough blood flow. It can also show how well the heart muscle is pumping.

A nuclear stress test is an imaging test that shows how blood goes to the heart at rest and during exercise. It uses a small amount of radioactive material, called a tracer or radiotracer. The substance is given by IV. An imaging machine takes pictures of how the tracer moves through the heart arteries. This helps find areas of poor blood flow or d...
This test may be done if you are being treated for heart disease or you have symptoms such as chest pain or shortness of breath. A nuclear stress test is often done to: 1. Diagnose coronary artery disease.The coronary arteries are the major blood vessels that supply the heart with blood, oxygen and nutrients. Coronary artery disease develops when t...
A nuclear stress test is generally safe. Complications are rare, but there is some risk. Complications might include: 1. Irregular heartbeats, also called arrhythmias.Those that occur during a stress test usually go away shortly after exercising ends or the medicine wears off. Life-threatening ones are rare. 2. Low blood pressure.Blood pressure may...
A nuclear stress test uses a substance called a radioactive tracer. It's given by IV. Then the health care provider takes two sets of pictures of the heart — one at rest and another after exercise. A nuclear stress test can take two or more hours. It depends on the radioactive tracer and imaging tests used.
Your health care provider compares the two sets of pictures taken during your nuclear stress test. The pictures show how blood flows through your heart while at rest and during physical activity. Your care provider talks to you about your test results. The results could show: 1. Typical blood flow during exercise and rest.You might not need any mor...

What is a Persantine MIBI? The goal of this procedure is to assess your coronary vessel health via diagnostic imaging by using radioactive tracers. These tracers are generally safe when used for medical purposes. This diagnostic cardiology test is designed help the clinician determine the current status of a patient's heart.
