摘　　要：目的 :回顾性分析了子宫内膜癌的磁共振成像 (MRI)表现和手术病理结果 ,探讨MRI在子宫内膜癌的术前分期和肌层浸润中的诊断价值。方法 :1 9例子宫内膜癌的诊断和分期均经手术和病理检查确诊 ,术前MRI检查采取横断位和矢状位的T1W和T2W成像 ,子宫内膜癌MRI分期按 1 988年FIGO分期原则。结果 :MRI分期的准确率达 78 9% ,其中对Ⅰ期的准确率为 92 .8% ,Ⅱ期的准确率为 1 0 0 % ,Ⅰ期和Ⅱ期的总准确率为 93 .7% ;对肌层浸润定位的准确率为85 .7%。结论 :MRI是子宫内膜癌术前分期和肌层浸润定位的一种优越方法。Objectives:To evaluate the value of magnetic resonance imaging(MRI)for staging before operation and localization of myometrial invasion in patients with endometrial carcinoma cases.Methods: Nineteen cases of endeometrial carcinoma were examined by MRI before operation and compared with the pathological findings.Results: The study showed that the accuracy of MRI for staging of endometrial carcinoma before operation was 78.9%,the total accuracy for stage Ⅰ and stage Ⅱ was 93.7%. And the accuracy for localization of myometrial invasion was 85.7%.Conclusions: MRI was a superior method for staging before operation and localization of myometrial invasion to endometrial carcinoma,it plays an important role for clinical doctors establishing the scheme of thrapy.
