The clinical use of nuclear cardiology for the assessment of myocardial ischemia continues to grow at an unprecedented rate. Part of the reason for this growth is the technical advances in single photon emission computerized tomography (SPECT). SPECT has been shown to provide high contrast images superior to planar imaging techniques. An important and recent technical advancement in SPECT has been ECG-gated myocardial perfusion SPECT to generate simultaneous myocardial perfusion and function information from a single study. Automated, quantitative techniques have facilitated the widespread...
