Fig. 7From: Comparison of diagnostic performance of four software packages for phase dyssynchrony analysis in gated myocardial perfusion SPECTThe sensitivity, specificity, and accuracy of ROC analysis in bandwidth (a), phase SD (b), and entropy (c). The sensitivity, specificity, and accuracy were computed by QGS, ECTb, 4DM, and cREPO.
