The feasibility of DKI in the human kidneys has been
demonstrated recently. We performed DKI using 3 b values
with 15 directions in 11 renal allografts recipients.
Our results showed FA was significantly greater in
medulla than in cortex, while cortical Ka showed
significant greater values than medullary Ka. Cortical
MK, Ka, Kr and medullary Ka correlated with eGFR
negatively and significantly. In conclusion, it is
possible that DK imaging may serve as an effective model
for functional evaluation of transplanted kidneys.
