Quantitative results for the automatic segmentation. The results from the automatic segmentation in comparison with the one randomly chosen manual segmentation are given in the left column (a,c,e) and the results from the manual observers in the right column (b,d,f). (a) and (b) show the correspondence in mean T2* with the gray identity line. Plots (c) and (d) compare the Dice coefficient for all participants and (e) and (f) the mean T2* over GA. The gray lines in (c-d) illustrate the mean Dice coefficients of the automatic versus manual 0.58, $n=108$) and inter-rater (0.68, $n=84$) comparison. As before, the results from the normal cohort are shown in black and the results from the abnormal cohort with mustard triangles. Units: GA in weeks, T2* in ms.
