彩色多普勒血流显像对恶性滋养细胞肿瘤化疗疗效的观察

Clinical efficacy of color Doppler flow imaging in the treatment of malignant trophobiastic tumors

摘要: 目的　探讨彩色多普勒血流显像 (CDFI)对恶性滋养细胞肿瘤治疗疗效的观察价值。方法　对30例恶性滋养细胞肿瘤化疗前后进行检测, 观察其流量情况有PD(脉冲多普勒 )检测病变区血流速度, 测定RI值。结果　化疗前病变区血流异常丰富, 呈现低阻性血流, 化疗后病变区血流信号明显减少, 化疗前后RI值明显有差异 (P <0 .0 5 )。结论　彩色多普勒血流显像对观察恶性滋养细胞肿瘤疗效有十分重要的临床价值。

Abstract: Objective To detect the valne of color Doppler flow imaging (CDFI) in the treatment of malignant trophobiastic tumors. Methods Thirty patients were examined before and after chemotherapy. The changes of blood flow velocitvy and its resistance index were measured by CDFI. Results In CDFI, before chemotherapy, a colorful and rich low resistance flow spectrum was observed in the tumor area. After chemotherapy, the blood flow message decreased significantly ( P < 0.05 ). Conclusion CDFI is useful for obs...
