Abstract
OBJECTIVE: The purpose of this study was to evaluate the ability of MR cholangiography to reveal the characteristics of biliary abnormalities found in primary sclerosing cholangitis. CONCLUSION: Our results suggest that MR cholangiography could be useful in the diagnosis of primary sclerosing cholangitis. Slightly dilated peripheral bile ducts unconnected to the central ducts in several hepatic segments are a characteristic MR sign of primary sclerosing cholangitis. However, other studies are necessary to establish the usefulness of MR cholangiography in relation to other imaging techniques for evaluating primary sclerosing cholangitis.
