摘　　要：目的:评价在新修订的FIGO分期系统下,磁共振成像(magnetic resonance imaging,MRI)在子宫内膜癌术前分期及肌层浸润深度判定中的作用。方法:对36例子宫内膜癌进行术前MRI分期和肌层浸润深度判定,并与手术病理分期对照。结果:MRI术前分期诊断准确率为91.7%(33/36)。MRI诊断无肌层侵犯、浅肌层侵犯和深肌层侵犯的敏感性、特异性、准确率分别为50%、85.7%、77.8%;84.4%、76.5%、80.6%;80.0%、100%、94.4%。MRI区分Ⅰa期(无肌层侵犯和浅肌层侵犯)和Ⅰb期(深肌层浸润)的诊断准确率为94.4%(34/36)。结论:MRI对子宫内膜癌术前分期及肌层浸润深度的判断准确率较高,具有很高的应用价值。Objective：To evaluate the role of magnetic resonance imageing（MRI） in preoperative assessment of the staging and the depth of myometrial invasion of endometrial carcinoma.Methods： Thirty six cases of endometrial carcinoma were examined by MRI before operation,and the pathological findings were compared with MRI findings.Results：The accuracy of MRI in staging endometrial carcinoma was 91.7%（33/36）.The sensitivity,specificity and accuracy of the MRI imaging in assessment of non-myometrial invasion,superficial myometrial invasion,deep myometrial invasion of endometrial carcinoma were 50%,85.7%,77.8%;84.4%,76.5%,80.6%;80.0%,100%,94.4%,respectively.The accuracy for distinguishing stagesⅠa andⅠb was 94.4%（34/36）.Conclusion：MRI is of high value in assessing the depth of myometrial invasion and staging in patients with endometrial carcinoma.
