Fig. 2From: Comparison of diagnostic performance of four software packages for phase dyssynchrony analysis in gated myocardial perfusion SPECTThe box-and-whisker plots of bandwidth (a), phase SD (b), and entropy (c) in patients with suspected LV dyssynchrony (n = 34). These phase parameters were computed with QGS, ECTb, 4DM, and cREPO.
