Evaluation Of The MRI In Diagnosis And Staging Of Cervical Carcinoma

Objective:To observation the finding of MRI of cervical carcinoma and to evaluate the value of MR imaging in preoperative diagnosis staging of cervical carcinoma。Methods:(1)Pelvic MR imaging was performed in 88 patients who were suspected with cervical carcinoma,84 patients were comfirmed by pathological examination. MRI scan which was included SE T1WI, TSE T2WI, SPIR TSE T2WI and Gd-DTPA enhanced in SE T1WI sequence with axial, sagital and coronal image display. Their were analyzed for location extension of the primary tumor and signal characteristics. Sensitivity of different sequence for deteting tumor were compared. (2)Among them 53 cases had surgery within 2 weeks after MR examination, The comparison between the preoperative MR evaluations for tumor and pathology results were made for each cases.(3)The value of ADC were compared between the tumour's center,edge,uterine mucilage and survived normal uterine muscular. Results:The sensitivity of cervical carcinoma in SE T1WI, TSE T2WI,SPIRT SET2WI, Gd-DTPA enhanced SE T1WI was 36.9%,90.47%,90.47%,85.71%,total sensitivity was 94.05%.The accuracy of MRI staging of cervical carcinoma was 82.00%.Ⅰb determine of accuracy rate was 100%,Ⅱa judge accuracy rate was 78.26%,Ⅱb determine the accuracy rate of 80.00%. Parametrial invasion was 80% sensitivity and specificity was 86.84%. the value of ADC were compared and show, Cancer Center> Cancer edge> uterine mucus> survived normal uterine muscular, and the four sets of data were statistically significant differences in ADC values (P< 0.05).Conclusion:MRI can clearly show the morphological features and the extension of cervical carcinoma, and DWI is also very important in functional imaging. So that it should be regarded as a routine examination.
