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.
