OBJECTIVE: To compare the validities of magnetic resonance imaging (MRI) and @entity419 positron emission tomography/computed tomography ((18)F-FDG PET/CT) in preoperative @entity6962 . METHODS: Pathologic results of @entity1313 and paraaortic and pelvic @entity1600 ( @entity1600 ) areas were compared with the preoperative image findings. Differences in the validity parameters of both images were compared using McNemar test. RESULTS: For detecting @entity1313 (n=56), the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for @entity419 PET/CT versus MRI were 98.1% versus 98.1% (P=1.000), 33.3% versus 100% (P=0.157), 94.6% versus 98.2% (P=0.500), 96.3% versus 100%, and 50% versus 75%, respectively. For paraaortic @entity1600 areas, the values were 77.8% versus 51.9% (P=0.016), 90.2% versus 100% (P=0.025), 85.9% versus 83.3% (P=0.774), 80.8% versus 100%, and 88.5% versus 79.7%, respectively. For pelvic @entity1600 areas, the values were 61.1% versus 50% (P=0.125), 86.8% versus 89.5% (P=0.727), 78.6% versus 76.8% (P=0.774), 68.8% versus 69.2%, and 82.5% versus 79.1%, respectively. For extrauterine disease, the @entity1 -based values for @entity419 PET/CT were 100%, 78.9%, 85.7%, 69.2%, and 100%, respectively. CONCLUSION: In @entity1 with @entity6962 , @entity8984 -FDG PET/CT is comparable to MRI in detecting primary uterine lesions. For predicting @entity1600 @entity3 , though @entity419 PET/CT might be insufficient for replacing lymphadenectomy or MRI, it might allow lymphadenectomy to be omitted in poor surgical candidates. For detecting extrauterine @entity3 , it could also be useful to identify unsuspected disease.
