Introduction: Myocardial perfusion scintigraphy (MPS) is an established non-invasive technique for the diagnosis and management of patients with suspected or known coronary artery disease. Because of the wealth of prognostic data, MPS single photon emission computed tomography (SPECT) is the most commonly used functional test to detect inducible ischaemia.

Feb 01, 2013 Although several myocardial perfusion PET tracers are available, the most widely used in clinical practice are rubidium-82 (82 Rb) and nitrogen-13-ammonia (13 N-ammonia). Rubidium-82 82 Rb is a potassium analog that is a generator product with a physical half-life of 76 s and kinetic properties similar to those of Thallium-201 ( 201 Tl) in SPECT.

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.
