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。
OBJECTIVE: To retrospectively analyze the magnetic resonance imaging (MRI) findings and pathological findings of endometrial carcinoma and to evaluate the diagnostic value of MRI in the preoperative staging and myometrial invasion of endometrial cancer. Methods: The diagnosis and staging of endometrial carcinoma in 19 cases were confirmed by operation and pathological examination. T1W and T2W images of transverse and sagittal planes were taken before MRI examination. MRI staging of endometrial cancer was based on FIGO stage of 1988 in principle. Results: The accuracy of MRI staging was 78.9%, of which 92.8% for stage Ⅰ, 100% for stage Ⅱ, and 93.7% for stage Ⅰ and Ⅱ. The accuracy of myometrial invasion and localization was 85.7%. Conclusion: MRI is a superior method of preoperative staging and myometrial invasion and localization of endometrial cancer.
