Segmentation quality measures (sensitivity and precision) between automatic and expert reference lesion segmentation for MSmetrix, LST and Lesion-TOADS for 20 MS patients.

Automatic method	Sensitivity	Precision
MSmetrix	0.57 ± 0.13	0.83 ± 0.11
LST	0.50 ± 0.22*	0.70 ± 0.09**
Lesion-TOADS	0.50 ± 0.08**	0.81 ± 0.17

Sensitivity and precision are presented in mean ± standard deviation.

^*Values significantly different from MSmetrix (paired t-test with p < 0.05 significance level).
