Table 4.

The correlation coefficients between the mean thickness (t_mean), maximum thickness (t_max), wall area (WA) associated with four methods and the gold standard (i.e., corresponding measurements of the first manual segmentation, M1). M2 represents the second manual segmentation. SB1, SB2, SA0, and SA5 boundaries generated by semiautomatic segmentation methods (see caption of Table TABLE II.).

	tmean	tmax	WA
M2	0.65	0.57	0.54
SB1	0.39	0.36	0.38
SB2	0.30	0.24	0.24
SA0	0.61	0.55	0.60
SA5	0.65	0.60	0.54
