Carcinoma of the uterine cervix and endometrium are common gynecologic malignancies. Both carcinomas are staged and managed by means of the International Federation of Gynecology and Obstetrics (FIGO) staging system. In uterine cervical cancer, the FIGO staging system is determined preoperatively by limited conventional procedures. Although this system is effective for early stage disease, it has inherent inaccuracies in advanced stage diseases and does not address nodal involvement. CT and MR imaging are widely used as comprehensive imaging modalities to evaluate tumor size and extent, and nodal involvement. MR imaging is an excellent modality for depicting invasive cervical carcinoma and can provide objective measurement of tumor volume, and provides high negative predictive value for parametrial invasion and stage IVA disease. In contrast, endometrial cancer is surgically staged. Beside recognition of the important prognostic factors, including histologic subtype and grade, accurate assessment of the tumor extent on preoperative MR imaging is expected to greatly optimize surgical procedure and therapeutic strategy. Contrast-enhanced MR imaging can offer “one stop” examination for evaluating the depth of myometrial invasion cervical invasion and nodal metastases. Evaluation of myometrial invasion on MR imaging may be an alternative to gross inspection of the uterus during the surgery.
