This study investigated the feasibility of predicting early renal function impairment after renal transplantation based on an intravoxel incoherent motion imaging (IVIM)diffusion weighted imaging (DWI)radiomics model. For noninvasive detection of kidney function impairment at an early stage, IVIM-DWI applies a bi-exponential model to evaluate both capillary perfusion and tissue diffusion. The overall accuracy of the radiomics model was 79.3%, with 73.3% sensitivity and 85.7% specificity in distinguishing renal function impairment after renal transplantation. These results demonstrate the potential of a radiomics model for a reliable non-invasive diagnosis of renal transplant function.
