Pancreas segmentations in patients from each of the five visceral fat
groups. Segmentation performance is better for patients with higher
visceral fat (group 5 being the highest). Visceral fat percentages at
the L1 level for the specific patients shown here were 9.81% in group 1,
13.72% in group 2, 20.19% in group 3, 27.88% in group 4, and 32.42% in
group 5; Dice similarity coefficients were 0.36, 0.62, 0.78, 0.81, and
0.86, respectively. In the automated segmentation images, the green area
indicates full segmentation and the yellow area indicates segmentation
after erosion. Obs. = observer.
