Nuclear Stress Test

A nuclear stress test, also known as a myocardial perfusion imaging (MPI) test or cardiac stress test with nuclear imaging, is a non-invasive diagnostic procedure used to evaluate the blood flow to the heart muscle. It helps to determine if there are any areas of the heart that are not receiving adequate blood supply, which could indicate the presence of coronary artery disease (CAD) or other heart-related conditions.

The nuclear stress test involves two main components: the stress phase and the imaging phase.
