The aim of this study was to assess the liver parenchyma by evaluating the regional variability, the measurement stability and the correlations of parameters calculated from IVIM and DKI models using different ROIs. The results demonstrated that S8, S5/8, S5 and S3 delegating different level of liver tissue can be chosen as the representative area in assessing the IVIM-DKI imaging of the liver. ADC, MD, MK and D with lower deviation were suitable for the quantitative evaluation of liver tissue and can be used to reflect different sides of the microstructure of the hepatic parenchyma.
