St. Luke's-Roosevelt Hospital Center

Standard full-time SPECT will be processed using FBP and compared to 3-minute stress and 5-minute rest scans processed with WBR. The following scan parameters will be evaluated: image quality; perfusion defect extent, severity, and reversibility; transient ischemic dilatation; left ventricular end-diastolic volume; left ventricular end-systolic volume; left ventricular ejection fraction; and regional wall motion and wall thickening abnormalities. These parameters will be assessed visually by experienced Nuclear physicians (at least 2 blinded readers) and quantitatively using several different commercially available software programs.
