Nuclear Stress Test/Myocardial Perfusion Imaging (MPI)
More commonly referred to as a Nuclear Stress Test, Myocardial Perfusion Imaging (MPI) is a non-invasive imaging test that shows how well blood flows through the heart muscle. A nuclear stress test 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.
Nuclear stress tests are generally safe for most people. MPI studies expose you to a low dose of X-rays. Experts disagree if X-rays at such low doses can cause cancer, but the possibility exists that no dose of X-rays, however low, is completely safe. Do not take the test if your risk for a heart attack is high, or if there are other reasons (chest discomfort) that indicate you might have heart trouble. If you're pregnant or think you might be pregnant, or if you're a nursing mother, tell your doctor before taking this test. It could be harmful to an unborn baby.

The test takes between 3 and 4 hours. Our clinic performs the resting part of the test first, and exercise tests afterwards on the same day.
Make an appointment with your doctor to discuss the test results and next steps.
