Imaging of pancreatic adenocarcinoma: update on staging/resectability

Because of the evolution of treatment strategies staging criteria for pancreatic cancer now emphasize arterial involvement for determining unresectable disease. Preoperative therapy may improve the likelihood of margin negative resections of borderline resectable tumors. Cross-sectional imaging is crucial for correctly staging patients. Magnetic resonance (MR) imaging and computed tomography (CT) are probably comparable, with MR imaging probably offering an advantage for identifying liver metastases. Positron emission tomography/CT and endoscopic ultrasound may be helpful for problem solving. Clear and concise reporting of imaging findings is important. Several national organizations are developing templates to standardize the reporting of imaging findings.
