To assess the cortex perfusion and diffusion parameters derived from ASL and IVIM in allografts after kidney transplantation. 32 allograft renal divided in two groups according to the eGFR,and 16 healthy volunteers were involved, scanned using ASLIVIM sequence. ASL derived RBF and IVIM derived Dfast, Dslow and PF were compared between three groups by ANOVA with Bonferroni test. Dslow,PF and RBF has statistic difference between three groups (P <0.05).However, the differences between groups were higher in RBF than in Dslow and PF.Compared with IVIM, cortex perfusion information provided by ASL was more sensitive to evaluate the renal function.
