1) To recognize the role of MRI in the follow up of incidental cystic pancreatic lesions. 2) To understand the potential advantages and disadvantages of a short MRCP protocol for the follow up of incidental cystic pancreatic lesions.

The diagnosis of incidental cystic pancreatic lesions has increased dramatically in the last decades due to widespread use of cross-sectional imaging and improvements in image quality. While the vast majority of these lesions exhibit a benign behavior a minority of them can evolve into invasive malignancies. This has led to the development and implementation of practice guidelines for the follow up of these lesions by several major medical organizations, all of which recognize serial imaging as the pillar of such strategies. Magnetic resonance cholangiopancreatography (MRCP) offers several advantages for the follow up of incidental pancreatic cystic lesions including excellent soft-tissue contrast and sensitivity to detect fluid and delineate ductal structures of the pancreaticobiliary system, and the lack ionizing radiation. However, several qualities may challenge its broad implementation including long acquisition times, cost, and concerns about the repeated administration of gadolinium-based contrast agents during serial examinations. In this talk we will review the potential advantages and disadvantages of a short MRCP protocol for the follow up of incidental cystic pancreatic lesions.
