ABSTRACT
This paper is aimed to investigate the influence of gated myocardial perfusion imaging (G-MPI) with 8- and 16-frame acquisition models on the assessment of left ventricular function. Patients prepared for stress and rest G-MPI were prospectively recruited from January 2010 to January 2011 in the Department of Nuclear Medicine of West China Hospital, Sichuan University. Two separate G-MPI studies, one with 8 and the other with 16 frames, were simultaneously acquired during a single gantry orbit using Concurrent Imaging technique. We calculated the left ventricular ejection fraction (EF) and volumes using the Auto Quant software. Forty-eight patients (29 men, 19 women; average age 51 +/- 16 years old) were finally analyzed. The differences in left ventricular EF between 8- and 16-frame were small 3.27% (95% CI 6.41%-0.12%) for post-stress and 3.13% (95% CI 5.93%-0.32%) for rest. Both using 8 and 16 frames, there were significantly larger volumes and lower EF in patients with stress-induced ischemia than without. As for detecting left ventricular EF, 8-frame and 16-frame acquisition models should not be mutually alternated.
