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.
