Diagnosis of Primary Sclerosing Cholangitis
Magnetic resonance cholangiopancreatography (MRCP) Primary sclerosing cholangitis (PSC) is suspected in patients with unexplained abnormalities in Laboratory Tests of the Liver and Gallbladder , particularly in those with Imaging of the hepatobiliary system begins with ultrasonography to exclude extrahepatic biliary obstruction. Although ultrasonography or CT can show ductal dilation, diagnosis requires cholangiography to show multiple strictures and dilations in the intrahepatic and extrahepatic bile ducts. Cholangiography should begin with Magnetic resonance imaging (MRI) (MRCP). Adults with PSC, even in the absence of cirrhosis, should undergo Imaging Tests of the Liver and Gallbladder (ultrasound, abdominal computed tomography, or magnetic resonance imaging/magnetic resonance cholangiopancreatography) every 6 to 12 months to screen for Colorectal Cancer Screening with 1.Bowlus CL, Lim JK, Lindor KD: AGA Clinical practice update on surveillance for hepatobiliary cancers in patients with primary sclerosing cholangitis: Expert review.Clin Gastroenterol Hepatol17(12):2416-2422, 2019. doi: 10.1016/j.cgh.2019.07.011
