目的 比较分析阴道超声、磁共 振成像(MRI)在子宫内膜癌诊治中的临床 意义。方法 以2015年1月-2016年7月经病 理证实58例子宫内膜癌患者为研究对象， 术前均接受阴道超声、MRI检查，以术后 病理结果为标准，比较阴道超声、MRI对 术前临床分期的诊断准确率；同时观察不 同检查方法影像学表现。结果 术后病理 分期：Ia期40例，Ib期12例，II期4例， IVa期2例。以术后病理分期为金标准， 阴道超声对术前临床分期诊断总准确率 86.21%，MRI对术前临床分期诊断总准确 率87.93%，两者比较差异无统计学意义 （P＞0.05)。结论 阴道超声、MRI对子宫 内膜癌术前分期判断准确率均较高，能为 子宫内膜癌术前手术方案制定提供重要依 据。

Objective To compare the clinical significance of transvaginal ultrasound and magnetic resonance imaging (MRI) in the diagnosis and treatment of endometrial carcinoma. Methods Fifty-eight patients with endometrial carcinoma confirmed by pathology between January 2015 and July 2016 were examined by transvaginal ultrasound and MRI examination before operation. With postoperative pathological results as the standard, the accuracy was compared between transvaginal ultrasound and MRI in the diagnosis of preoperative staging. The findings of different imaging examinations were observed. Results As for postoperative pathological stage, there were 40 cases in stage Ia, 12 cases in stage Ib, 4 cases in stage II and 2 cases in stage IVa. With postoperative pathological staging as the golden standard, the total accuracy rate of transvaginal ultrasound in the diagnosis of preoperative clinical staging was 86.21%, and of MRI was 87.93% (P>0.05). Conclusion The accuracy rate of both transvaginal ultrasound and MRI in the diagnosis of preoperative staging of endometrial carcinoma are high, which can provide important basis for development of preoperative operation of endometrial carcinoma
