  1. Note: D true diffusivity, D* pseudodiffusion coefficient, f perfusion fraction, ADC apparent diffusion coefficient. Data are presented as the mean ± standard deviation. The P values in bold type are of statistical significance. D, ADCs are presented in × 10−5 mm2/s, D* is presented in × 10−3 mm2/s, and f is presented as a percentage. CO, renal cortex, OS, outer stripe of the outer medulla, IS, inner stripe of the outer medulla, IM, internal medulla
  2. P1 indicates a difference in the changes in IVIM parameters over time between the two groups
  3. P2 indicates a difference in the difference of the IVIM parametric means between the two groups over time
  4. P3 indicates a difference in the IVIM parametric means between the two groups
