WebDec 1, 2004 · 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. WebJun 1, 2024 · LVEF quantification by ERNA has been shown to have excellent reproducibility ( 6, 7 ), with inter- and intraobserver variability <5% ( 8 ). As such, it is often used in serial assessment of LVEF to assess for cardiotoxicity among patients undergoing chemotherapy (primarily with anthracyclines).
