Fig. 1 —Crescent-shaped regions of interest (ROIs) in subendocardium of 55-year-old woman who was a healthy control subject were placed manually on 2D short-axis and vertical long-axis cardiac images, according to American Heart Association classification. We measured myocardial thickness for 17 segments at systole and diastole and calculated mean values for them. Thickness of ROI was defined as half of mean value at systole and diastole.
