Conclusion

An understanding of the key descriptors of PDAC and their importance, especially in relation to the perivascular spread of disease, provides essential information that helps determine treatment options. Borderline resectable PDAC is an important clinical entity because of the large percentage of patients presenting with stage III disease and the increasing number of treatment options available for such patients. With the evolution of newer surgical and chemoradiation therapy options, the defnition of borderline resectable disease continues to evolve; and optimized accuracy of preoperative staging for metastases and an accurate assessment of disease response, especially to new promising chemotherapeutic agents, are high-yield areas for affecting patient outcomes. A comprehensive description of the relationship between PDAC and the peripancreatic vessels and their variants can be obtained by careful evaluation of the multidetector CT images in multiple planes to include all of the descriptors that surgeons may need for surgical planning and for the administration of neoadjuvant therapy. The use of standardized terminology and a radiologic template to document the multidetector CT fndings for PDAC can limit the subjective evaluation of the tumorvessel relationship and mandates the provision of key information that may otherwise be missed.
