Preoperative Magnetic Resonance Imaging Staging of Uterine Cervical Carcinoma: Results of Prospective Study

Objective To determine the accuracy of the preoperative staging of uterine cervical cancer by magnetic resonance (MR) imaging in 115 patients in a prospective study. Methods A prospective study was performed in 115 patients who underwent MR imaging at 1.5 T before surgery or biopsy. Histopathologic findings were correlated with MR imaging results for all patients. Results The accuracy of preoperative tumor staging by MR imaging in the 115 patients was 77%. In terms of the evaluation of parametrial status, this study had an accuracy of 94% and a sensitivity of 38%. The accuracy and sensitivity of MR imaging for vaginal invasion were 81% and 87%, respectively. In terms of lymph node metastasis, this study had an accuracy of 97% and a sensitivity of 36%. Conclusion Magnetic resonance imaging has high accuracy in the preoperative staging of uterine cervical cancer.
