  1. Global analysis was performed on the entire left ventricular myocardium. Per-segment analysis divided the myocardium into 6 regional segments. Values are reported as mean ± standard deviation across all subjects. (FOV) field of view, (MBF) myocardial blood flow, (PN) physiological noise, (TSNR) temporal signal-to-noise, (N) number of pixels within each segment.
