Statistical comparison of manual and computer segmentation on different planes.

$P$-values from paired two sample for means $t$-test
Plane	Comparison	Area difference (%)	Dice	Avg dist error (mm)	Max dist error (mm)
Sagittal	Manual versus registration versus manual versus HNN	$p<0.05$	$p<0.05$	$p<0.05$	$p<0.05$
Coronal	Manual versus registration w/heart versus manual versus HNN w/heart	$p<0.05$	$p<0.05$	$p<0.05$	$p<0.05$
Axial	Manual versus registration w/heart versus manual versus HNN w/heart	$p<0.05$	$p<0.05$	$p<0.05$	$p<0.05$
