摘　　要：目的研究阴道超声与磁共振成像(MRI)在子宫内膜癌术前分期中的诊断价值。方法以我院2013年1月-2015年6月收治的50例子宫内膜癌患者为研究对象,均经手术病理证实,术前均行阴道超声及MRI检查,以手术病理结果为对照,分析两种检查方式对子宫内膜癌术前分期诊断结果。结果手术病理分期:I期36例,II期14例。以术后病理分期为金标准,术前超声检查对I期、II期诊断准确率分别为86.1%、85.7%;术前MRI检查对I期、II期诊断准确率分别为88.9%、92.9%;阴道超声、MRI对子宫内膜癌术前分期准确率分别为86.0%、90.0%,两组比较差异无统计学意义(χ2=0.38,P=0.54>0.05)。结论阴道超声、MRI对子宫内膜癌术前分期准确度均较高。Objective To study the diagnostic value of transvaginal ultrasound and magnetic resonance imaging（MRI） in the preoperative staging of endometrial carcinoma. Methods50 cases of endometrial cancer patients who were admitted into the hospital during Jan. 2013 to Jun. 2015 were selected as the research objects. All the cases were confirmed by operation and pathology. Transvaginal ultrasound and MRI examination were performed before surgery. Taking the operative and pathological findings as control, the diagnostic results of the two kinds of test modes in the preoperative staging of endometrial carcinoma were analyzed. Results Surgical pathologic staging showed that there were 36 cases at stage I and 14 cases at stage II. With postoperative pathological staging as the gold standard, the diagnostic accuracy rates of preoperative ultrasonography for stage I and II were 86.1% and 85.7% while of MRI were 88.9% and 92.9%. The accuracy rates of transvaginal ultrasound and MRI for preoperative staging of uterine endometrial cancer were 86.0% and 90.0%, respectively. The difference between the two groups was not statistically significant（χ2=0.38, P=0.540.05）. Conclusion Conclusion The accuracy rates of transvaginal ultrasonography and MRI in preoperative staging of endometrial carcinoma was higher.
