We studied 17 renal patients with RAS detected by using CE-MRA and 15 control subjects with 1.5 T MRI scanner adding DTI to the standard protocol. The comparison between the two groups showed that medullary ADC/FA in the study group were significantly lower than in the control group (P=0.034 and 0.022, respectively); there was no significant difference for the other parameters. This suggests that DTI could be a useful tool in evaluating renal alteration in hemodynamic RAS.
