Associations between MRI T1 mapping, liver stiffness, quantitative MRCP, and laboratory biomarkers in children and young adults with autoimmune liver disease

In paediatric and young adult with autoimmune liver disease AILD, multiparametric MRI (LiverMultiScan) and MRCP+ showed robust associations with laboratory markers. cT1 correlated with markers of liver disease activity, and cT1 IQR appeared less confounded than MRE. MRCP+ biliary metrics discriminated AIH from PSC/ASC, supporting combined imaging for noninvasive stratification and monitoring.
