- Bias = mean difference; EDV = end-diastolic volume; EF = ejection fraction; ESV = end-systolic volume; Mid = mid-cavity; SDD = standard deviation of the difference. Values computed by performing a Bland-Altman analysis. Results presented in mL and % error (ie, percentage of the total left ventricular volume calculated by manual delineation).
- # EF computed by rejecting the clinically unacceptable contours (ie, the area was set to zero for these contours).
