Figure 1
(A) Histogram of propagation angle (PA) values with discrimination of infarcted (PA > 4°) and remote (PA ≤ 4°) myocardium. Inset shows a PA map of a left ventricular short-axis slice illustrating the increase in PA in the infarct. (B-D) Least-squares fit of infarct size by G60, FWHM, and 5-SD versus that of PA. (E-H) Segmentation of infarcted myocardium by PA, G60, FWHM, and 5-SD. The 5-SD and FWHM metrics include a portion of the border zone and therefore overestimate the extent of the infarct.
