Mono-exponential ADC and IVIM-related diffusion coefficient D of the kidney slightly increase with diffusion time as opposed to ADC of skeletal muscle. Pseudodiffusion coefficient D* shows the strongest dependence on diffusion time among the investigated parameters.

Mono-exponential ADC and IVIM-related parameters (D, D*) measured in the renal cortex (top row), renal medulla (middle row) and skeletal muscle (bottom row).

Perfusion fraction f_p obtained from the IVIM analysis in the renal cortex (top row), medulla (middle row), and skeletal muscle (bottom row).
