Background Information: Pancreatic adenocarcinoma is an aggressive malignancy and accurate determination of the extent of disease on imaging studies is a crucial step in treatment planning. Imaging also plays a crucial role in response assessment after treatment. It is essential for radiologists to be familiar with updates in imaging techniques and standard reporting methods to define the extent of disease and response assessment.

Educational Goals/Teaching Points: The purpose of this educational exhibit is to review the current role of imaging in staging of pancreatic cancer imaging, including advanced imaging techniques. We discuss recent advances and updates in imaging of pancreatic cancer and highlight key imaging features of pancreatic cancer staging using an interactive quiz-based format.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: Updates of technical advances (DECT, DWI) and discussion of current criteria and updates in assessment of pancreatic cancer resectability are presented. Participants will review prognostic markers and predictors of treatment response on imaging with an interactive case-based imaging quiz to highlight role of imaging in pancreatic cancer.

Conclusion: Imaging plays a crucial role in pretreatment evaluation and response assessment in pancreatic cancer. Because of variability in the terminology used by radiologists, adoption of a standardized radiology reporting template is important. Radiologists also need to be familiar with the use of novel imaging methods for response assessment.
