Comparison of Monoexponential, Biexponential, Stretched-Exponential, and Kurtosis Models of Diffusion-Weighted Imaging in Differentiation of Renal Solid Masses.

Although both the biexponential and kurtosis models obtained much poorer fit performances in relation in both benign and malignant lesions, it might be partly due to the tumor types, which did not have an extremely significant intravoxel incoherent motion or kurtosis effect, or the choice of the number and range of b-values used in the study.
