中文摘要：

目的：对经阴道彩色多普勒超声对盆腔良恶性肿瘤的临床诊断价值进行分析及探讨。方法：对恶性肿瘤患者采用经阴道彩色多普勒超声进行诊断，同时将检测结果与良性肿瘤患者及正常对照组进行对比。结果：恶性肿瘤患者血流RI值明显低于良性肿瘤及对照组的患者（P〈0．05），良恶性肿瘤不同分期的血流信号具有差异性（P〈0．05）。结论：经阴道彩色多普勒超声综合分析血液中RI值、血管分布类型、脉冲频谱舒张期切迹等指标，可有效提高盆腔癌良恶性肿瘤的鉴别的灵敏性及特异性。

英文摘要：

Objectives： to analyze and discuss the clinical value of transvaginal color Doppler ultrasound in treating benign and malignant pelvic tumors. Methods： We diagnosed patients with malignant tumors by transvaginal color Doppler ultrasound and compared the detection results with those of the patients with benign tumors and people in healthy conditions as the control group. Results： The blood RI value of the patients with malignant tumors was significantly lower than that of the patients in the other two groups （P 〈 0. 05 ）. Different stages of blood flow signal of benign and malignant tumors were different （ P 〈 0. 05 ）. Conclusions： Indicators analyzed by transvaginal color Doppler ultrasound, including blood RI, vascular distribution type, pulse spectrum of diastolic notching can be more effective in detecting benign and malignant pelvic tumors.
