XXXX : staging with CT and MR imaging.

@entity43 @entity1 @entity5
PURPOSE: To evaluate @entity43 resectability with computed tomography (CT) or magnetic resonance (MR) imaging. MATERIALS AND METHODS: Eighty-two @entity1 underwent CT (n = 43) or MR imaging (n = 50); eleven of these 82 underwent both. Imaging was performed within 4 weeks of surgical staging. Radiologic, surgical, and histopathologic findings were compared. RESULTS: Overall staging accuracy was similar for CT and MR imaging (77% [33 of 43] vs 78% [39 of 50]). Evaluation of pelvic @entity5 extent was better with MR imaging than with CT. There was no difference in detection of abdominal disease. Most mesenteric and small-bowel implants were not detected with either CT or MR imaging. For CT, the positive predictive value for @entity5 nonresectability was 100% (three of three @entity1 ); the negative predictive value was 92% (37 of 40 @entity1 ). The positive and negative predictive values for MR imaging were 91% (10 of 11 @entity1 ) and 97% (38 of 39 @entity1 ). CONCLUSION: While the staging accuracy of both CT and MR imaging is only moderate, prediction of @entity5 resectability is excellent.
