What is myocardial perfusion SPECT?
Myocardial perfusion SPECT (Single-photon emission computed tomography) is a well-established test to detect coronary artery diseases and evaluate the heart’s blood supply. It is also called a cardiac stress-rest test.
SPECT is a nuclear medicine topographic imaging technique which uses gamma rays, and provides 3-dimensional (3D) images.
Two sets of images showing blood flow are obtained: the first set following a period of rest, and the second set following a period of stress, such as exercises on a treadmill.
Speaking of the procedures, your vein may be injected into a radiotracer which is made of a radioactive isotope and a pharmaceutical agent.
Myocardial perfusion SPECT can not only be used to evaluate damage caused by myocardial infarction, but also used to asses the presence and extent of myocardial ischemia.
