Since DWI with different models may demonstrate different aspects of tissue properties, it should be valuable to compare and explore their roles in renal tumors. To our knowledge, however, no comparison of these different diffusion imaging approaches for the differential diagnosis in renal tumors has been investigated so far. The purpose of this study was to quantitatively compare and evaluate the potential clinical value of various diffusion parameters obtained from monoexponential, biexponential, and stretched exponential DWI models for differentiation of MFAML from ccRCC.
