Abstract:
Objective To discuss the value of MRI in the assessment of diagnosis and staging of cervical carcinoma. To compare MRI diagnosis value before surgery and pathology staging after surgery in uterine cervical carcinoma. Methods Pelvic MRI were performed in 50 patients with cervical carcinoma. The pathological type included 47 cases of squamous cell carcinoma, 2 cases of adenocarcinoma and 1 cases adeno-squamous carcinoma. The MRI scanning included axial SE T1WI, axial , sagittal and coronal FSE T2WI ,and axial , sagittal and coronal enhanced or dynamic contrast-enhanced MR. MR staging were compared with surgical pathologic staging after surgery in 38 patients. Results The accuracy of MR imaging in stage Ⅰ - ⅡA of cervical cancer were 82.35 %. These patients performed an operation of hysterectomy or subtotal hysterectomy surgery. The accuracy of MR imaging in stage ⅢA-ⅣB were 100 %. The accuracy of MRI in total stage were 84.21%. Conclusion MR imaging can show the local tumors and extension of the cervical cancer clearly on multiple planes and angles. Preoperative staging with high accuracy, MR1 is conducive to preoperative evaluation, surgical plan formulation and selection.
