About this trial
This study aims to use positron emission tomography (PET)/magnetic resonance imaging (MRI) to diagnose and quantify PSC-related biliary tract fibrosis and to improve upon the currently available non-invasive diagnostic capabilities by investigating the ability of combined PET/MRI to detect and quantify fibrosis using a novel collagen-binding radiotracer. Specifically, the investigators will be comparing \[68Ga\]CBP8- and \[18F\]-FAPI-74 PET/MRI to a liver transient elastography scan in the diagnosis of biliary tree fibrosis.
