Evaluation of left ventricular systolic and diastolic function by fractional area change in cine CMR. End-diastolic and end-systolic phase are visually determined in datasets from short-axis cine images at mid papillary muscle, and phase number during 30% of diastole is calculated by multiplying total phase number during diastole by 0.3 and rounding up values. Left ventricular (LV) endocardial contours are then manually traced only on cine images of end-diastolic phase, end-systolic phase, and phase at 30% of diastole. The LV systolic fractional area change (systolic-index,%) and fractional area change during the first 30% of diastole (diastolic-index %) are calculated.
