What is a myocardial perfusion imaging test? Myocardial perfusion imaging (MPI) is a non-invasive imaging test that shows how well blood flows through (perfuses) your heart muscle. It can show areas of the heart muscle that aren't getting enough blood flow. This test is often called a nuclear stress test. It can also show how well the heart muscle is pumping Myocardial perfusion imaging (MPI) is a noninvasive method that utilizes radioisotopes to assess regional myocardial blood flow, function, and viability. MPI is used to identify ischemic or infarcted regions by detecting differences in blood flow during stress compared with rest Myocardial perfusion is an imaging test. It's also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, it may be done to find areas of damaged heart muscle. This test may be done during rest and while you exercise Reliable and rapid diagnosis is important to reduce the number of deaths and allow introduction of appropriate therapy at a very early stage of the disease. Given that the last EANM Technologist's Guide entitled Myocardial Perfusion Imaging was released way back in 2004, it is certainly time for this new book A myocardial perfusion imaging measures the blood flow and function of the heart. Individuals getting this test usually receive a tracer or a small amount of a radioactive substance, that will be used to trace problems in the heart. Healthy heart tissues will absorb the radioactive material and damaged tissues will be highlighted by it

Gated MPS pro - vides important information on the extent and severity of myocardial perfusion abnor-malities, including myocardial ischaemia Current assessment for myocardial ischemia is typically performed with noninvasive stress imaging including stress echocardiography, single photon emission computed tomography (SPECT), or magnetic resonance imaging (MRI) myocardial perfusion imaging (MPI) The word Myocardial is used to describe the muscles of the heart. Myocardial Perfusion, also called Nuclear Myocardial Perfusion Imaging or Nuclear Stress Test, is a nuclear cardiology procedure that involves, putting pharmaceutical radioactive tracers, a radioactive, into the muscle of the heart to show images of the nutritional blood flow to. The use of PET (positron emission tomography) tracers for myocardial perfusion imaging (MPI) began in the 1980s . Already in those very early years, together with the visual assessment of the uptake pattern, quantitative methods for measuring myocardial blood flow (MBF) were proposed and developed [2,3,4,5]. However, due to logistic constraints caused by the high costs of imaging systems and the limited availability of on-site cyclotrons needed for the production of then available.

Introduction. As part of the functional assessment of the coronary vasculature, the evaluation of myocardial perfusion represents a major gatekeeper to percutaneous coronary intervention (PCI) in the work-up of suspected obstructive coronary artery disease (CAD) and several invasive and non-invasive imaging techniques are available today. 1-3 Myocardial perfusion reserve (MPR) quantifies the. Myocardial perfusion imaging, medical procedure that uses radioactive tracers, primarily thallium, to detect abnormalities in the blood supply to the heart muscle. Myocardial perfusion imaging is used to diagnose myocardial ischemia, which is caused by a reduced supply of blood to the heart; myocardial infarction, or heart attack, which is an interruption of blood flow to an area of the heart. Radionuclide myocardial perfusion imaging uses an intravenously administered radio-pharmaceutical to image myocardial perfusion during stimulation of the perfusion system and at rest. The images are acquired using a gamma camera and tomographic imaging is preferred over planar imaging because of the three dimensional nature of the images and their superior contrast resolution.
