This study examines the repeatability of quantitative measures obtained from the lower legs using a diffusion kurtosis tensor imaging sequence with a scan time of just 13 minutes. Test-retest data was acquired, and kurtosis parameters were calculated for both sets of data. Muscle groups were segmented, and repeatability was assessed by muscle group. In both the medial gastrocnemius and tibialis anterior, kurtosis fractional anisotropy and fractional anisotropy showed highest repeatability, as well as mean diffusivity in the medial gastrocnemius.
