Comparative study of 68 MRI staging with clinical and pathologic staging of cervical carcinoma

Abstract

Objective To analyze the MRI features of cervical carcinoma,and evaluate the value of MRI in staging of cervical carcinoma. Methods Pelvic MRI imaging was performed in 68 patients with cervical carcinoma proved by pathology.MRI images were analyzed for location,size,signal characteristics,extension of the primary tumor and surrounding tissue. MRI findings were compared with clinical staging and surgical pathologic findings.Results Based on MRI staging,stage Ⅰa was seen in 2 cases,Ⅰb in 5 cases,Ⅱa in 34 cases,Ⅱb in12 cases,Ⅲa in 4 cases,Ⅲb in 5 cases,Ⅳa in 4 cases,Ⅳb in 2 cases. The accuracy of MRI imaging in determination of tumor location was 100%, invasion the parauterine tissue was 86.7%. The total accuracy of MRI imaging staging was 88%.Conclusions MRI can well demonstrate the size and extension of the cervical carcinoma, MRI has important value in staging of cervical carcinoma,and very helpful in making the therapeutic plan.It is suggested that MRI should be regarded as a conventional study for the patients with cerivical carcinoma.
