J Comput Assist Tomogr. Sep-Oct 2004;28(5):620-7. doi: 10.1097/01.rct.0000138007.77725.0a.

Abstract

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.
