title: Variability of corpus callosal area measurements from midsagittal MR images: effect of subject placement within the scanner.
abstract: Variation in corpus callosum area measured from midsagittal MR images was evaluated in 12 healthy subjects who were each imaged four to seven times. Statistically significant differences between measurements of the same subject were found on 47% of the images, with an average difference of 5.9% between images.
