恶性滋养细胞肿瘤的彩色多普勒声像图表现及诊断价值

ULTRASONIC FEATURES AND DIAGNOSIS VALUE OF COLOR DOPPLER FLOW IMAGING IN MALIGNANT TROPHOBLASTIC TUMORS

对２３例恶性滋养细胞肿瘤进行彩色多普勒显像和血流阻力指数（ＲＩ）测定，并以３２例子宫肌瘤和５例子宫腺肌症作为对照组。表明子宫病灶内及周围显示丰富的斑点状彩色血流信号和ＲＩ＜０．４，与对照组有显著差异（Ｐ＜０．０１）。提示彩色多普勒可为诊断恶性滋养细胞肿瘤及与子宫良性病变鉴别的重要检查方法。

Twenty-three cases of malignant trophoblastic tumors were detected with color doppler flow imaging,the resistive indexes(RI)of blood flow were also measured,and thirty-three cases of myoma of uteres and five cases of internal endomeriosis were as a control group.The results indicate:aboundant spotted-like colored blood flow signals are showed in internal focus of uterus and its peripheral area,including the low resistive blood flow.There are significant difference between them(P<0.01).The blood flow change in focus of uterus can be identical with pelvic arteriography.Consequently, we recommen that color doppler flow imaging can be as a main method for diagnosing maligant trophoblastic tumors and different diagnosis with other tumors of uterus.
