Table 2.
Comparison of the parameters of the intravoxel incoherent motion (IVIM), diffusion kurtosis (DKI) and combined IVIM-DKI imaging models before (B/w) and after (A/w) water administration obtained in our study and in the previous studies. Means and standard deviations for the region of interest (ROI) analysis over all subjects are shown.
