MRI is a powerful tool for detection, characterization, and surveillance of both cystic pancreatic lesions, such as serous and mucinous tumors, and intraductal papillary mucinous tumors, as well as neuroendocrine tumors. Because the MR signal is so sensitive to fluid, fluids in the cystic lesions as well as in the ducts are well depicted. Historically, neuroendocrine tumors have been more challenging to evaluate because of their small size and the short time window between when an intravenously injected contrast material reaches the tumor and the rest of the normal pancreas. However, Stanford researchers have developed a suite of tools that provide unprecedented high resolution images with fast snapshots that have helped detect these small lesions.
