Shi Y, et al. - This prospective study evaluated the value of magnetic resonance elastography (MRE) in patients with autoimmune pancreatitis (AIP) and in the differentiation of AIP from pancreatic ductal adenocarcinoma (PDAC) by analyzing data of 14 AIP patients, 26 PDAC patients, and 14 healthy volunteers. The findings from the present study suggested that pancreatic stiffness was significantly higher in AIP than in healthy pancreas and significantly lower in AIP than in PDAC. Data reported that MRE displays promise as a quantitative imaging method for differentiating AIP from PDAC and for monitoring the treatment response in AIP.
