摘　　要：目的研究MRI与USG在判断临床Ⅰ期子宫内膜癌患者子宫肌层浸润深度中的临床价值并对两种检查方法进行比较。资料与方法32例Ⅰ期子宫内膜癌患者术前均行MRI与USG检查;MRI与超声分别对32例患者进行临床分期,并与术后病理结果进行对照分析。统计学方法采用列联表的χ2检验及配对资料的χ2检验。结果32例患者病理分期:Ⅰa期6例,Ⅰb期18例,Ⅰc期8例。MRI、USG对判断子宫内膜癌有无肌层浸润的准确率分别为92%(24/26)、85%(22/26)。MRI分期与病理分期相比符合率为78%(25/32),超声分期与病理分期相比符合率为47%(15/32)。对Ⅰb的分期诊断,MRI与USG有明显统计学差异。结论MRI对判断临床Ⅰ期子宫内膜癌的进一步分期诊断优于USG,其中对Ⅰb的分级判断较USG有明显差别。Objective To evaluate the clinical value of magnetic resonance imaging （MRI） and ultrasound sonography （USG） in judging the myometfium invasion of clinical staging Ⅰ endometrial carcinoma. According to pathologic results, compare the advantages of two methods. Materials and Methods 32 eases of endometrial carcinoma had been approved to be clinical staging Ⅰ , and all of them had been evaluated by MRI and USG before operation. The results of MRI and USG were compared with pathologic results. The paired X^2 test statistical method was used. Results According to 1988 FIGO staging, pathologic examination showed that 6 cases of 32 patients had tumor confined to the myometrium （stage Ⅰa）, 18 cases had involvement of inner half of the myometfium （stage Ⅰb）, and 8 had involvement of the outer half of the myometfium （stage Ⅰc）. The diagnostic accuracies of myometfium Invasion of endometrial carcinoma by MRI and USG were 92 % （24/26）, 85 % （22/26） respectively, compared with the staging of pathology, the diagnostic accuracies of MRI and USG were 78% （25/32）, 47 % （15/32） respectively. There was significant difference in the evaluation of stage Ⅰb between MRI and USG. Conclusion MRI is superior to USG in estimating the invasion of myometrium; There is significant difference in the evaluation of stage Ⅰb between MRI and USG.
