The techniques of nuclear cardiology permit the noninvasive imaging of myocardial perfusion under stress and resting conditions and of resting regional and global function using radionuclide imaging agents and gamma or positron cameras with associated computer processing. Myocardial perfusion imaging is the most commonly performed nuclear cardiology technique, and it is employed most often in conjunction with either exercise or pharmacologic stress intended to produce flow heterogeneity between relatively hypoperfused and normally perfused myocardial regions. Radionuclide angiography, in which technetium-99m (99m Tc)-labeled red blood cells or other 99m Tc-labeled agents are injected intravenously, is used for measurement of left ventricular ejection fraction (LVEF) and assessment of regional wall motion.
