One hundred and twenty seven patients with uterine cervical carcinoma underwent computed tomography(CT) and magnetic resonance(MR) imaging. Followed by surgical exploration. MR imaging was superior to CT in visualization of the tumor, for parametrial evaluation, and for tumor staging. MR imaging had an accuracy of 74% in the assessment of thickness of cervical stromal invasion, The accuracy rates for parametrial evaluation were 78% for CT and 88% for MR imaging. The overall accuracy rates for tumor staging were 68% for CT and 80% for MR imaging. Our findings suggest that MR imaging is supperior to CT in preoperative stanign of uterine cervical carcinoma.
