Graphs show receiver operating characteristic curves of different MRI and laboratory markers for diagnosis of significant fibrosis in patients with primary sclerosing cholangitis (≥ F2). Curves are given for hepatic T1 relaxation times (area under curve [AUC]: 0.711), hepatic ECV (AUC: 0.858), hepatic T2 relaxation times (AUC: 0.686), APRI (AUC: 0.787), FIB-4 score (AUC: 0.588), ALT/AST ratio (de-Ritis) (AUC: 0.570), and MELD score (AUC: 0.680). APRI: AST-to-Platelet Ratio Index, FIB-4 score: Fibrosis-4 score, MELD: Model of End Stage Liver Disease
