Fig. 3From: Time-modified OSEM algorithm for more robust assessment of left ventricular dyssynchrony with phase analysis in ECG-gated myocardial perfusion SPECTScatterplots of activity ratio (AR) vs. changes of bandwidth (∆BW), standard deviation (∆StD) and entropy (∆ENT) between OSEM and TOSEM. Pearson’s correlation coefficients (r) and regression line equations are displayedBack to article page
