The potential of Diffusional Kurtosis Imaging (DKI) for differentiation of patients with pathological CSF (MCIp-CSF) from MCI-patients without pathological CSF (MCInp-CSF) and from controls was probed for using ROI-based analysis. Diffusivity changes were present in some areas. Kurtosis parameters MK and RK did not outperform diffusion parameters MD and FA.
