Analysis of the clinical value of magnetic resonance imaging in cervical cancer

Objective To analyze the magnetic resonance imaging(MRI) features of cervical carcinoma,and explore the value of MRI in the staging of uterine cervical carcinoma.Methods Fifty-two cases with cervical carcinoma were collected from our hospital before MRI examination which were observed the tumor location,size,signal character-istics and parametrial infiltration.MRI findings were compared with clinical staging and surgical pathologic findings to evaluate the value of MRI imaging in the staging.Results There were 4 cases of ⅠA period of cervical cancer that MRI examination did not show lesions.There were 48 cases of ⅠB period above of cervical cancer that MRI inspection demonstrated the focus of infection.The stage were as follows: ⅠB(26 cases),ⅡA(11 cases),ⅡB(6 cases),ⅢA(3 cases),ⅢB(1 cases),ⅣA(1 cases).There were 43 cases identical with pathological staging.The sensitivity and specificity for parauterine extension were 92% and 90%.The total accuracy of MRI staging was 83%.Conclusion MRI examination can find all the cases of ⅠB period above of cervical cancer,clearly show that vaginal involvement,parametrial infiltration and lymph node metastasis.Cervical cancer diagnosis and staging accuracy rate is significantly higher than clinica,MRI examination has the high application value.
