Searching for indicators of malignancy in pancreatic intraductal papillary mucinous neoplasms: the value of 18FDG-PET confirmed.

Background: Malignancy in intraductal papillary mucinous neoplasms (IPMN) of the pancreas may be predicted on the basis of a number of clinical and radiologic features, which have raised sensitivity but result in a specificity as low as 20-50%. We sought to confirm the additional value of (18)F-18-fluorodeoxyglucose-positron emission tomography ((18)FDG-PET) in diagnostic accuracy of imaging-based IPMN malignancy assessment.

Methods: This prospective uncontrolled case series contained 44 patients with IPMN undergoing comprehensive diagnostic evaluation, including magnetic resonance cholangiopancreatography and (18)FDG-PET.
