In this issue of Circulation: Cardiovascular Imaging, Bulluck et al introduce simultaneous positron emission tomography and magnetic resonance (PET-MR) imaging as a sophisticated research tool to correlate cardiac function, area of risk, metabolism, and infarct size in patients with acute myocardial infarction. Imaging is increasingly applied for the noninvasive characterization of acute and ch...

Electrocardiographically gated myocardial perfusion SPECT (GSPECT) is a state-of-the-art technique for the combined evaluation of myocardial perfusion and left ventricular function within a single study. It is currently one of the most commonly performed cardiology procedures in a nuclear medicine department. Automation of the image processing and quantification has made this technique highly r...

Background A novel technology has been developed for ultrafast (UF) singlephoton emission computed tomography (SPECT) myocardial perfusion imaging by employing a pin-hole collimation design and multiple cadmium zinc telluride crystal arrays. The purpose of this study was to compare myocardial perfusion imaging obtained by UF-SPECT with standard (S) SPECT in patients with known or suspected coro...
