The measures of CBF among the gray matter, white matter, and whole matter in the hemodialysis baseline group and hemodialysis follow up group. ***Significant group differences with Tukey’s test correction, P < 0.001, ** Significant group differences with Tukey’s test correction, P < 0.01, * Significant group differences with Tukey’s test correction, P < 0.05. (A) CBF of decreased CBF group in the grey matter, white matter and whole matter was higher than increased CBF group (P < 0.01) and higher than HC group (P < 0.01) in hemodialysis baseline. (B) CBF of decreased CBF group in the grey matter, white matter and whole matter was lower than increased CBF group (P < 0.01) and lower than HC group (P < 0.01) in hemodialysis follow-up. CBF = cerebral blood flow; HC = healthy control; GM = grey matter; WM = white matter
