Looking for Myocardial Perfusion Imaging (MPI)? At the WELL Health Clinic Network, we provide quick and convenient access to the care you need. Our dedicated healthcare providers are committed to delivering exceptional care, assisting you every step of the way.
Myocardial Perfusion Imaging (MPI), also known as a Nuclear Stress Test, determines how well the coronary arteries deliver blood to your heart and identify 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 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 a valuable tool for patients experiencing chest discomfort, as it helps determine if the discomfort stems from insufficient blood flow to the heart muscle due to narrowed or blocked arteries (angina). Although MPI doesn’t directly visualize the heart arteries, it provides your doctor with a reliable assessment of any blockages and their extent.
During your nuclear stress test
The test consists of two parts, which you may complete in one or two days.
Rest Study: 1.5 – 2 hours
During this portion of the test, the technologist will administer a small amount of radioactive tracer via intravenous injection. Your bloodstream carries the tracer to your heart. There are no side effects with this injection.
Around 15-45 minutes after the injection, the technologist will use a special gamma camera to take pictures of your heart for approximately 20 minutes. During the test, you may need to sit in a specially designed-chair or lie on a bed. It’s important to remain still during this time to avoid blurring the images.
Stress Study: 2-2.5 Hours
After your nuclear stress test
You will be able to return to your normal activities when the test is complete, unless your physician or technician tells you otherwise. You can drive after the test. If you are travelling by plane, train or crossing the border within one week after your test, please inform the technologist.
