Effect of augmenting the CNN‐B with CNN‐SC alone, the CNN‐WV alone, and both CNN‐SP on network performance for the hippocampus segmentation experiment

	Dice (%)	MHD (mm)
CNN‐B	90.2 (2.8)	0.27 (0.10)
CNN‐Ba	87.2 (3.2)	4.59 (2.47)
CNN‐WV	90.9 (2.4)	0.26 (0.13)
CNN‐WVa	90.6 (2.5)	0.54 (0.59)
CNN‐SC	91.3 (2.1)	0.24 (0.09)
CNN‐SCa	90.1 (2.6)	0.64 (0.40)
CNN‐SP	91.5 (2.0)	0.23 (0.08)
CNN‐SPa	91.4 (2.1)	0.25 (0.14)

Note: Mean Dice and MHD values over both left and right hippocampi are reported, with SDs in parentheses.

Abbreviations: CNN, convolutional neural network; CNN‐B, baseline CNN; CNN‐SC, CNN with spatial coordinates; CNN‐SP, CNN with both spatial priors; CNN‐WV, CNN with working volume; MHD, modified Hausdorff distance.
