Lee S, et al. - Researchers assessed the diagnostic performance of CT vs MRI in differentiating non-diffuse-type autoimmune pancreatitis (AIP) from pancreatic ductal adenocarcinoma (PDA) by analyzing data of 61 patients with non-diffuse-type AIP and 122 patients with PDA who had dynamic contrast-enhanced CT and MRI with MR pancreatography. In differentiating non-diffuse-type AIP from PDA, MRI has better diagnostic performance than CT. In demonstrating key distinguishing features of non-diffuse-type AIP and PDA, MRI is superior to CT. Discrete pancreatic mass and MPD stricture were seen significantly more often using MRI vs CT in PDA.
