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.
