Primary sclerosing cholangitis (PSC) is a chronic cholestatic liver disease characterized by biliary inflammation and fibrosis leading to bile duct strictures, cirrhosis, and carries an increased risk of hepatobiliary malignancies. Magnetic resonance imaging (MRI) with magnetic resonance cholangiopancreatography (MRCP) is the imaging modality of choice in PSC. As an evolving technology, MRI has other potential applications in the care and study of those patients with PSC. In this review, the authors aim to provide a technical overview on MRI/MRCP and related technologies, summarize its contemporary use in PSC, and discuss its evolving role to predict outcomes and look ahead toward emerging MRI technologies relevant to PSC.
