Myocardial perfusion imaging. Myocardial perfusion scan (also referred to as MPI) is a nuclear medicine procedure that illustrates the function of the heart muscle (myocardium). It evaluates many heart conditions, such as coronary artery disease (CAD), hypertrophic cardiomyopathy and heart wall motion abnormalities. The function of the myocardium is also evaluated by calculating the left ventricular ejection fraction (LVEF) of the heart. This scan is done in conjunction with a cardiac stress test.
Pulse volume recording (PVR) is a non-invasive imaging test that evaluates the lower or upper extremity blood flow. They are actually the more complete form of ankle brachial index, because they test more areas of the limb and not just the flow at the end. Pulse volume recording is a functional test. This means that it does not examine specific blood vessels, but rather assesses the sum of all blood flow to the examined limb.
