WebNuclear medicine has long played an important role in the noninvasive evaluation of known or suspected coronary artery disease. The development of single photon emission computed tomography (SPECT) led to improved assessments of myocardial perfusion, and the use of electrocardiographic gating made accurate measurements of ventricular wall …

WebJul 8, 2024 · SPECT is now used routinely for myocardial perfusion studies. Its advantages include a true three-dimensional display of the distribution of the radionuclide within the myocardium, improved image contrast because of the elimination of overlying structures, and the potential for quantification of tracer uptake. There are 17 segments that have a reasonably consistent vascular supply from one of the three main coronary arteries (RCA, LAD and LCx), but significant anatomic variation does exist. This standard segmentation model can be used in cardiac nuclear tests, computed tomography, magnetic resonance … See more In the long axis, the left ventricle is divided into equal thirds named the basal, mid andapicalthirds. The tip of the apex forms a separate final segment. When these thirds are viewed in … See more The inability to visualize the whole chamber often necessitates utilization of anatomical landmarks to delineate the thirds: 1. basal: mitral annulus to the tips of the papillary musclesin end-diastole 2. mid: along the length … See more hounds chenille vest
