To guage the diagnostic performance of intravoxel incoherent movement (IVIM) diffusion-weighted imaging (DWI) for grading hepatic inflammation. ). The reference standard had been histopathological analysis of hepatic irritation grade, steatosis grade, and fibrosis stage. Intraclass correlation coefficients (ICC), univariate and multivariate correlation analyses, and areas under receiver operating feature curves (AUC) were evaluated. Parameters f, D, and D* had ICCs of 0.860, 0.839, and 0.916, respectively. Correlations of f, D, and D* with swelling grade were ρ = - relationship between swelling and perfusion fraction.• IVIM parameters derived from DWI show with 10 b-values tend to be reproducible for liver structure characterization. • This retrospective two-center research indicated that perfusion fraction supplied good diagnostic performance for distinguishing dichotomized grades of infection. • Fibrosis is an important confounder on the connection between irritation and perfusion fraction.Teleradiology solutions tend to be playing an important role through the COVID-19 outbreak. Activity at radiology departments needs to be maintained and adjusted to this
