目的 观察子宫内膜癌的磁共振 (MRI)影像特点，评估MRI在子宫内膜癌中 的诊断价值。方法 纳入2012年3月～2014 年3月我院经手术病理证实为子宫内膜癌 的72例患者作为观察对象，回顾性分析其 临床资料，依照国际妇产科协会(FIGO)制 定的子宫内膜癌分期标准，将子宫内膜癌 患者术前分期与术后病理结果进行对照， 总结子宫内膜癌的MRI影像学特点及其诊 断价值。结果 本组72例患者，术前MRI诊 断分期Ⅰ期44例，Ⅱ期22例，Ⅲ期6例； 术后病理分期Ⅰ期48例，Ⅱ期18例，Ⅲ期 6例；Ⅰ期符合率为91.67%，Ⅱ期符合率 为81.81%，Ⅲ期符合率为100.00%。结论 在子宫内膜癌的临床诊断与术前病理分期 中应用MRI扫描，可准确鉴别患者子宫肌 层的受侵犯程度、范围及预后状况，且术 前分期符合率高，与其他诊断方式相比， 操作简单，准确性高，可为术前评估提供 参照，以优化治疗效果，改善患者预后。

Objective To summarize the magnetic resonance imaging (MRI) features and to assess the diagnostic value of magnetic resonance imaging in endometrial carcinoma. Methods 72 patients with endometrial carcinoma comfirmed by surgery and pathology admitted into the hospital from March 2012 to March 2014 were selected as the research object. The clinical datum of the patients were retrospectively analyzed. According to the staging criteria of endometrial carcinoma made by international federation of gynecology and obstetrics (FIGO), the results of preoperative staging and postoperative pathology of the patients were compared and the MRI features and its diagnostic value of endometrial carcinoma were summerized. Results Among the 72 patients, there were 44 cases of stage I, 22 cases of stage II and 6 cases of stage III in preoperative MRI staging; 48 cases of stage I, 18 cases of stage II and 6 cases of stage III in postoperative pathologic staging; the coincidence rate of stage I was 91.67%, stage II 81.81% and stage III 100%. Conclusion In the clinical diagnosis and preoperative pathological staging of endometrial carcinoma, to adopt MRI scanning can accurately identify the degree of mesometrium invasion, range and prognosis with high preoperative staging rate. Compared with other diagnostic methods, it is simple to operate and of high accuracy. It can provide a reference for preoperative evaluation to optimize treatment effect, improving the prognosis of patients.
