Evaluation of quantitative MRCP (MRCP+) for risk stratification of primary sclerosing cholangitis: comparison with morphological MRCP, MR elastography, and biochemical risk scores

In PSC, MRCP+ quantitative duct metrics correlated with biochemical risk scores and MR elastography, with performance comparable to ANALI morphological scores. Combining MRCP+ with ANALI or with MRE improved association with the Mayo Risk Score, supporting integrated imaging and morphology for noninvasive risk assessment.
