Early characterization of liver fibrosis has great clinical significance as it allows monitoring of treatment response to antifibrotic agents in patients with chronic liver disease. Most recently, high b-values diffusion-weighted imaging (DWI) based on the continuous-time random-walk (CTRW) model has been introduced. Compared to the healthy control group, the mean D, α, and β values were significantly lower in the hepatic fibrosis group. Spatial diffusion heterogeneity β showed the best diagnostic performance. This non-invasive method has the potential to realize efficient evaluation and improve clinical treatment decision-making.
