We collected 20 volunteers and 62 renal allograft recipients who underwent intravoxel incoherent motion (IVIM) and arterial spin labeling (ASL) MRI. Comparing cortical perfusion indices, ADCfast and PF derived from IVIM with RBF derived from ASL in native and transplanted kidneys. We found that mean cortical RBF exhibited a significant correlation with PF (R =0.50, P <0.05) in the native kidneys, but both with ADCfast (R =0.26, P <0.05) and PF (R =0.32, P <0.05) in renal allografts. ADCfast and PF are effective indices for monitoring renal perfusion, as well as RBF.
