Myocardial perfusion imaging (MPI) is a powerful tool for detection of impaired myocardial blood supply due to atherosclerotic lesions in the epicardial arteries. MPI is commonly conducted using single photon emission computed tomography (SPECT) with Tlor Tc-based tracers, under conditions of rest and hyperemic stress. Regions of high tracer uptake are assumed to be normally perfused, while regions with relatively low uptake (perfusion defects) typically reflect stenosis of the upstream… CONTINUE READING
