In this work we examine cine CMR data derived from a large, community-based cohort to determine: 1) the contribution of the basal LV slice(s) at ED to LV volumes and EF and 2) the effect of manual correction of automatically-detected LV contours on global LV functional parameters. Our results show that automatic myocardial contour detection for determination of LV volumes and EF is feasible and accurate in a large, population-based sample of adults. After inclusion of basal slice data, further manual corrections to the automatically-detected contours have minimal effect on the final outcome of global functional parameters.
