Usefulness of positron emission tomography (PET)/contrast-enhanced computed tomography (CE-CT) in discriminating between malignant and benign intraductal papillary mucinous neoplasms (IPMNs)

FDG uptake on PET is a useful new marker for malignancy in benign/malignant differentiation. Because PET/CE-CT imaging is a noninvasive imaging modality that can evaluate FDG uptake in addition to the conventional high-risk findings, we believe it should be the first-line method for determining therapeutic approaches to IPMN.
