Overview of the Role of Imaging in Pelvic Exenteration.

Pelvic exenteration is a radical surgery that is used in an attempt to cure patients with locally advanced central pelvic malignancies. Exenteration is a salvage operation that is considered only after other therapies, such as chemoradiation, have been exhausted. The high morbidity from exenteration's multiorgan resection warrants careful patient selection. Preoperative imaging plays a major role in the selection process, allowing the exclusion of patients with unresectable pelvic disease or distant metastases. Imaging is also crucial to surgical planning, providing the surgeon with a map of the distribution and extent of the pelvic disease.
