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.
