The role of MR imaging in determining surgical eligibility for pelvic exenteration.

Abstract

MR imaging may provide an accurate means of selecting patients considered for pelvic exenteration. MR accurately determined which patients should undergo the surgery, by demonstrating absence of sidewall abnormalities or adenopathy. Radiation changes could not be reliably distinguished from tumor involvement in those patients with sidewall abnormalities, however, especially in the first 6 to 12 months after treatment.
