The aim of this study is to investigate the MR imaging characteristics in patients with autoimmune pancreatitis (AIP), and to evaluate the role of MR imaging in the diagnosis of this entity in comparison with helical CT. MR imaging and dynamic helical CT were performed in 6 patients with AIP. The imaging features of AIP were reviewed and compared between MR imaging and helical CT. Our results indicate that MR imaging is superior to CT in demonstrating characteristic imaging features of AIP, particularly in showing capsulelike rim and diffuse irregular stricture of the pancreatic duct.
