Ectopic pancreas in upper gastrointestinal tract: MRI findings with emphasis on differentiation from submucosal tumor.

The article presents a study which evaluates the potential of magnetic resonance imaging (MRI) in differentiating ectopic pancreas from submucosal tumors in the upper gastrointestinal tract (UGI) tract. It is inferred that the gastric body was the most common location for submucosal tumors and the duodenum for ectopic pancreas. According to the study, MRI with diffusion-weighted imaging (DWI) is a valuable tool for differentiating ectopic pancreas from submucosal tumors.
