Fig. 2From: Association between white matter hyperintensities and altered cerebral blood flow in maintenance hemodialysis patients: a longitudinal studyExamples of different categories of WMH scoring from 0 to 3 in the periventricular and deep white matter areas and CW area. FLAIR (A-D) showed the WMH in the periventricular (red arrow) and deep white matter areas (blue arrow), and from left to right, the scores went from 0 to 3 by the Fazekas visual rating scale [21, 22]. FLAIR (E-H) showed the WMH in the lower-level CW area (marked red), and from left to right, the scores went from 0 to 3. FLAIR (I-L) showed the WMH in the up-level CW area (marked red), and from left to right, the scores went from 0 to 3. WMH = white matter hyperintensities; CW = cerebral watershedBack to article page
