Preoperative staging of uterine cervical carcinoma: comparison of CT and MRI in 99 patients

J Comput Assist Tomogr. Jul-Aug 1993;17(4):633-40. doi: 10.1097/00004728-199307000-00022.

Abstract

Objective: The aim of this study was to compare CT and MRI at 0.5 T in the preoperative staging of uterine cervical cancer in a large series of patients.

Materials and methods: Ninety-nine patients with uterine cervical carcinoma underwent CT, MRI, and surgical exploration.

Results: Both CT and MR findings were compared using surgical-pathologic findings as gold standards. Magnetic resonance imaging was superior to CT in tumor detection (sensitivity 75 vs. 51%, p < 0.005), in parametrial evaluation (accuracy 87 vs. 80%, p < 0.005), in overall tumor staging (accuracy 77 vs. 69%, p < 0.025), and in pelvic lymph node evaluation (accuracy 88 vs. 83%, p < 0.01). Magnetic resonance imaging had an accuracy of 76% in assessment of the thickness of cervical stromal invasion.

Conclusion: Magnetic resonance imaging was superior to CT in preoperative staging of uterine cervical carcinoma and MRI should be used instead of CT for preoperative staging of this disease.
