Web(Also called Nuclear SPECT, Exercise myoview, Persantine myoview) Purpose . Nuclear stress myocardial perfusion imaging (MPI) is a nuclear cardiology test that shows how well blood flows to the muscle of the heart (myocardium). This test is used to diagnose the presence or absence of coronary artery disease. WebMyocardial perfusion imaging (MPI) allows for noninvasive evaluation of coronary artery disease (CAD) by detecting flow-limiting disease and providing risk stratification. 1-3 …

WebJan 7, 2024 · Given that uptake and retention of single photon emission computed tomography (SPECT) myocardial perfusion tracers, such as thallium, sestamibi, and tetrofosmin, reflect intact sarcolemmal Na-K ATPase or mitochondrial function, it would be anticipated that there would be a nearly linear relationship with the percentage of normal … WebJul 31, 2015 · A SPECT scan of the heart is a noninvasive nuclear imaging test. It uses radioactive tracers that are injected into the blood to produce pictures of your heart. Doctors use SPECT to diagnose coronary artery disease and find out if a heart attack has occurred. SPECT can show how well blood is flowing to the heart and how well the heart is working. Myocardial perfusion SPECT is used to evaluate damage that might have been caused by a myocardial infarction (heart attack) and to assess the presence and extent of myocardial ischemia (reduced blood flow due to obstruction in the vessels). Your doctor will determine if a myocardial perfusion SPECT examination is necessary. top black sabbath albums
