Mean lesion volumes obtained with the different normalization methods (n = 49).
*Unmasked lesion volume (121,602 mm3, S.E. = 13,646) significantly smaller than lesion volumes obtained in all masked conditions (unsmoothed, precisely masked lesion volume = 126,322 mm3, S.E. = 14,056; smoothed, precisely masked lesion volume = 127,458 mm3, S.E. = 14,232; unsmoothed, roughly masked lesion volume = 125,863 mm3, S.E. = 13,975; smoothed, roughly masked lesion volume = 125,967 mm3, S.E. = 14,069).
