^*From linear regression including apparent diffusion coefficient (ADC) resolution as a categorical covariate with three levels (LOW, INT, HIGH). The medical evaluation bord (MEB) term is significant in the anterior corona radiata, but the trend indicates higher ADC in the MEB group for all of the regions of interest.
