Diffusion-weighted MR Imaging for the Assessment of Renal Function: Analysis Using Statistical Models Based on Truncated Gaussian and Gamma Distributions.

Although ADC obtained from the monoexponential model also showed a moderate positive correlation ( r = 0.73), Frac < 1.0 showed a trend towards a strong negative correlation with eGFR, which was stronger than that with ADC (truncated Gaussian model, r = –0.81; gamma model, r = –0.79).
