The diffusional kurtosis (Kapp) and the apparent diffusion coefficient (Dapp) were measured in the human calf muscle. Maps of Dapp and Kapp are shown and the time dependence of both values is reported. A dependence on the diffusion direction is visible for both values, but a higher anisotropy can be observed for Dapp than for Kapp. The kurtosis decreases at longer diffusion time. Absolute values of Kapp in the muscle tissue are much smaller than in white matter tissue in the brain.
