Table 4.

Performances of the overall correlative feature analysis method using leave-one-out (by lesion) validation, as well as the comparison with the distance feature alone. This table also shows the comparison between the overall performances of merged features obtained from radiologist-outlined and computer-segmented lesions. Same convention as Table 3.
