Volume and surface error metrics (see [18]) for the proposed pancreas segmentation method using threefold cross validation on 40 consecutive portal venous phase contrast-enhanced CT data

Method	Overlap (%)	Volume difference deviation (%)	Average distance deviation (mm)	RMS distance deviation (mm)	Max distance deviation (mm)
Detector only	52.2 ± 10.31	10.53 ± 3.73	2.58 ± 0.77	4.69 ± 1.15	23.62 ± 5.45
Final result	61.2 ± 9.08	5.62 ± 3.47	1.70 ± 0.71	3.10 ± 1.13	16.13 ± 5.18

Results are shown using the tissue detector only (2nd row) and using the whole segmentation pipeline (3rd row). Jaccard index was calculated to show the overlap of the segmentation result and the reference standard
