Diagnostic Value of MRI Proton Density Fat Fraction for Assessing Liver Steatosis in Chronic Viral C Hepatitis

Table 3

Multiple regression analysis. MRI PDFF is the dependent variable of the model. Histological FF and the histological grade of steatosis were the only two factors independently and significantly correlated to MRI PDFF. values below the level of statistical significance () are marked with the asterisk.
