WebThe three-dimensional images produced by this study are called perfusion images because they show which areas of the heart muscle are perfused, or supplied, with blood. The stress/rest MPI may also be referred to as a cardiac or nuclear stress test, a thallium scan or a sestamibi cardiac scan. A physician may perform a Stress/Rest MPI study to: WebMyocardial perfusion is an imaging test. It's also called a nuclear stress test.
