3．0T磁共振成像在老年宫颈癌患者术前诊断和分期中的价值

Value of 3. 0T MRI in the preoperative diagnosis and staging of elderly cervical carcinoma

目的探讨3．0T核磁共振成像技术（MRI）在宫颈癌诊断及分期中的应用价值。方法选取2010年5月至2012年2月在吉林大学白求恩第一医院就诊的73例老年宫颈癌患者，评价宫颈癌的MRI表现及癌肿对周围侵犯情况，比较MRI分期与术后病理分期之间的相关性。结果MRI均显示73例患者的病灶，MRI对宫颈癌的定位诊断准确率为100．0％，对宫旁侵犯的准确度为94．2％。52例宫颈癌手术患者MRI分期与术后病理分期比较总的准确度为88．5％（46例）；在IB期、ⅡA期、ⅡB期，MRI分期与术后病理的相关性良好（x2=61．43，P〈0．01）；在Ⅲ期和Ⅳ期宫颈癌与术后病理一致性较强，符合率为100．0％。结论MRI对宫颈癌病灶显示的准确率和术前分期的准确率高。

Objective To explore the of elderly cervical carcinoma. Methods value of 3.0T MRI in preoperative diagnosis and staging Totally 73 patients were enrolled in this trial. The MRI features of cervical carcinoma and invasion of adjacent tissue were evaluated, the correlation of MRI staging and pathological staging was studied. Results MRI showed lesions in 73 patients, the accuracy of diagnosis for uterine cervical carcinoma was 10G 0 %, for parametrial invasion was 94.2 %. The results of MRI staging of 52 cases showed the accuracy was 88.5~ （46 cases） as compared with postoperative pathology. The correlation between the MRI and postoperative pathology in the stages of I B, I1 A and ]] B uterine cervical cancer was very well（）~2 =61.43,P^0.01）, the consistency of MRI in the diagnosis of uterine cervical cancer in stage Ill and 1V with postoperative pathology was extremely strong（100%）. Conclusions The accuracy of diagnosis and staging for uterine cervical carcinoma is high in MRI imaging.
