子宫恶性肿瘤术前MRI检查的价值

Value of MRI in Diagnosing and Staging Uterine Malignant Tumors

目的 :探讨MRI检查对子宫恶性肿瘤的术前诊断及分期价值。方法 :对12例子宫恶性肿瘤患者术前行盆腔MRI检查 ,包括10例子宫内膜癌和2例胎盘部位恶性滋养细胞肿瘤。将MRI诊断结果与术后病理诊断比较。结果 :9例子宫内膜癌MRI检查能够清楚显示瘤灶的形态及大小 ,并对肌层、宫颈或邻近结构的侵犯做出正确分期 ,另1例未能发现肿瘤 ;2例胎盘部位恶性滋养细胞肿瘤也能确切显示瘤灶的部位和范围 ,与病理检查相符。结论 :MRI检查在子宫恶性肿瘤的诊断及分期中有重要的临床价值 。

Objective:To evaluate the value of MRI in diagnosing and staging uterine malignant tumors.Methods:Twelve female patients with uterine malignant tumors accepted MRI examination preoperatively,among whom11patients were performed Gd-DTPA enhanced MRI examination simulataneously.Then,the MRI diagnosis was compared with the pathologic diagnosis.Results:In9of10cases of endometrial carcinomas,MRI clearly showed the shape,size and signal appearance of the tumors,their invasion in myometrium,cervices and parauterine structures,and MRI correctly staged them.One of them was stage I endometrial carcinomas,MRI could not distinctly depict it.In2cases of placenta site trophoblastic tumor,MRI clearly showed the site and signal intensity of the tumors in the uterine cavity and their invasive scope in myometrium,which was acˉcorded with the pathologic diagnosis.Conclusion:MRI is valuable in diagnosing and staging uterine malignant tumors.But for the tumor in early stage that is localized in endometrium,it is limited.
