The renal ADCs with high b values (100 - 800 s/mm2) were investigated during the cardiac cycle. The average ADC of the renal medulla was higher than that of cortex ( P < 0.01). However a maximum renal arterial flow occurred at 60 ms after R-wave during the cardiac cycle, the changes of ADC with high b value showed no peak at the same time . The renal ADC with high b values was less influenced by renal blood flow.
