摘　　要：Importance:In the past few decades,there has been rapid advancements in imaging technologies that have become irreplaceable in the pre-operative assessment of patients with pancreatic tumors.Modern imaging modalities,including computed tomography(CT)and endoscopic ultrasound(EUS),can provide critical information of the absence or presence of metastatic disease in pancreatic cancer,as well as details on the local extent and resectability,allowing for the selection of stage appropriate treatments and pre-operatively determined surgical approach.Objective:The aim of this review is to discuss staging,resectability,and imaging for patients with pancreatic tumors.Evidence Review:A literature review was performed of articles relevant to the topics of staging,resectability,and imaging of pancreatic tumors.Imaging modalities included CT,EUS,magnetic resonance imaging(MRI),positron emission tomography(PET),antibody-based and narrow band imaging.Findings:CT pancreas protocol combined with EUS serve as the primary modalities in diagnosis,staging,and surgical planning in patients with pancreatic tumors.MRI is an alternative to CT with near equivalent utility in the pre-operative setting.In some circumstances,PET-CT may be a cost-effective initial study to detect distant disease.Conclusions and Relevance:Current imaging technologies play a critical role in the evaluation of patients with pancreatic tumors.Advances in the past 3 decades in imaging technologies have revolutionized the process of assessment of stage and resectability in patients with pancreatic tumors.Future imaging technologies will address current limitation in the evaluation of occult metastatic disease.
