摘　　要：目的探讨彩色多普勒超声（CDFI）评价恶性滋养细胞肿瘤（MTT）患者的子宫动脉血流动力学变化的临床应用价值。 方法对42例患者进行检测，观察其子宫动脉血流情况，检测子宫动脉PI值和RI值。 结果MTT患者的子宫动脉P10．25～3．08（中位数0．97），R10．25～0．90（巾位数0．61），与对照组相比，血流参数有显著的差异（P〈0．01）。若子宫动脉PI≤1，其诊断MTT敏感性是69％，特异性是61％；RI≤0．5，其诊断MTT的敏感性是88％，特异性是60％。42例MTT患者子宫病灶血流PI：0．24～2．09（中位数0．47），RI：0．21～0．85（中位数0．33）。化疗后，37例MTT患者异常血流逐渐减少，RI呈逐渐升高趋势。 结论彩色多普勒超声是评估MTT患者子宫动脉血流动力学改变的首选方法。Objective To evaluate the clinical value of color Doppler flow imaging （CDFI） in malignant trophoblastic tumor （MTT） . Methods Uteri of 42 patients were observed. Resistive index （RI） and pulsatility index （PI） in foci and uteri were determined. The results were compared with those of normal type. Results It showed that PI of the uteri artery was between0.25-3.08 （median0.97）, RI of the uteri artery was between0.25-0.90 （median0.61） in malignant trophoblastic tumor cases. For uteri artery, PIll, can provide 69% sensitivity and 61% specialty. RI≤ 0.5, can provide 88% sensitivity and 60% specialty. It showed that PI in loci was between 0.24-2.09 （median 0. 47）,and RI in loci was between 0.21-0.85 （median 0.33 ）. After chemotherapy, hypervascularity in 37 patients decreased, RI increased higher. Conclusions Color Doppler flow imaging was the first choice to evaluate the hemodynamic change in malignant trophoblastic tumor.
