Table 2 Derivation cohort—association between scar and phase analysis, univariable analysis

From: Phase analysis single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) detects dyssynchrony in myocardial scar and increases specificity of MPI

Variable No scar (N = 235) Scar (N = 105) p value
Entropy (%) 45.0 (39.0, 51.0) 51.0 (45.0, 62.0) < .001
Phase histogram bandwidth (°) 42.0 (36.0, 60.0) 54.0 (42.0, 96.0) < .001
Phase standard deviation (°) 11.9 (8.5, 19.5) 17.4 (10.6, 25.0) < .001
