Fig 1.

Example of ratings using the Fazekas scale. Arrows point to regions of WMHs, blue arrows indicate DWMH, red indicate PVH. The rating scores were defined as follows for DWMH: 0= absent, 1= discrete diffuse lesions, 2= beginning of confluence of foci, 3= large confluent areas. The rating scores were defined as follows for PVH: 0= absent, 1= caps or pencil-thin lining around ventricles, 2= smooth halo around ventricles, 3= irregular PVH extending into the deep white matter. Left (lesioned) hemisphere is lightened as it was not used for rating.
