Correlations of IVIM-DWI parameters and T2* with hepatic fat fraction (HFF) using two models.

Two models were used to assess the effect of hepatic fat fraction (HFF) on the IVIM-DWI parameters (Dslow, Dfast and ffast) or T2* measured in 11 patients and 8 segments (n = 88). The linear model assumed a linear relationship between HFF and the IVIM-DWI parameters or T2* (Y = a•HFF+b). The log-linear model assumed a linear relationship between the logarithmic of HFF and the IVIM-DWI parameters or T2* (Y = a•log(HFF)+b). Pearson’s correlations increased when the log-linear model was applied. *Indicates significant correlations.
