By analyzing cerebral blood flow (CBF) maps generated from arterial spin labeling (ASL) data averaged across 436 cognitively healthy middle-aged subjects from the CARDIA study, we characterized the CBF distribution in white matter. CBF is specifically decreased in periventricular regions in a pattern not reflective of partial volume effects as estimated from the structural MRI segmentation. White matter lesion frequency mapping based on Fluid Attenuated Inversion Recovery (FLAIR) images from the same cohort demonstrates that lesions tend to occur in regions where group averaged CBF is lowest.
