Compared to the traditional mono-exponential model, the application of more complex models (stretched exponential model, diffusional kurtosis model, and bi-exponential model) to analyze the renal diffusion weighted MRI data can result in valuable additional insight into pathological processes, for example, benign cysts and renal cell carcinoma. In this research, we compared these four different models to demonstrate that renal pathologies can be differentiated from healthy tissue by applying higher order diffusion models to DWI data consisting of multiple diffusion weightings.
