ACR Appropriateness Criteria® Staging and Follow-Up of Pancreatic Neuroendocrine Tumors

The authors aim to provide evidence-based recommendations for the imaging evaluation of pancreatic neuroendocrine tumors (PNET) across various clinical scenarios, including staging and follow-up. They emphasize the use of contrast-enhanced CT as the primary imaging modality, with MRI and DOTATATE PET/CT serving important roles in specific cases, particularly for liver evaluation and metastatic disease. The guidelines are informed by a systematic review of the literature and expert consensus to ensure appropriate imaging practices for optimizing patient management.
