We performed intravoxel incoherent motion(IVIM), arterial spin labeling(ASL) and T1 mapping MR imaging in 62 renal allograft recipients to determine the diagnostic values of each parameter in renal allograft function evaluation. We found that cortical ADC, ADCslow, ADCfast, PF and RBF were lower for allografts with impaired function than with good function, and T1 values were higher for allografts with impaired function than with good function (P <0.05). ADC derived from IVIM and RBF derived from ASL showed a higher diagnostic efficacy to discriminate between allografts with impaired function and allografts with good function.
