Performance of the computer-assisted WMHs segmentation method with the derivation cohort.

Note: Δ Vol. = (Auto. vol. – Semi-auto. vol.)/Semi-auto. vol.; Demar. = the lowest intensity of the WMHs demarcated by the neurologist; SI = similarity index; Sen. = sensitivity; Spe. = specificity; Stdev = standard deviation; L (or R) = left (or right) hemisphere containing WMHs only; L* (or R*) = left (or right) hemisphere containing both WMHs and cerebral infarct lesions.
