摘要
目的探讨彩色多普勒超声诊断颈部淋巴结病变的价值。方法应用彩色多普勒超声观测24例良性、21例恶性肿大淋巴结L／S比值、内部回声、CDFI及PWD频谱特征、血流分布。结果良性淋巴结L／S比值大于1．8，平均为2．04±0．24，RI为0．60±0．08；而恶性肿大淋巴结L／S比值小于1．8，平均为1．45±0．26，RI为0．74±0．07，二项指标比较均具有显著性差异（P〈0．05），良性淋巴结血流分支细少，走行规律，低阻力，而恶性肿大淋巴结呈不规则扭曲、紊乱血流，高阻力。结论彩色多普勒超声对颈部肿大淋巴结良、恶性的鉴别诊断具有较大意义，可作为首选方法。
Objective To evaluate the value of color Dopple ultrasonography in diagnosing cervical lymphadenopathy. Methods The manifestation, internal echo, L/S ratio, CDFI, RI frequency spectrum feature and the characteristics of the flow shape and distribution of the 24 benign lymph nodes and 21 malignant lymph nodes in cervix were studied with color Doppler ultrasound. Results The benign lymph node＇s L/S ratio was larger than 1.8 in average 2. 044±0.24 , RI was 0. 60±0.08 and the malignant lymph node＇s L/S ratio was lower than 1.8 in average 1.45±0.26, RI was 0.74±0.07, There were significant differences between the groups （P〈0. 05）. The distribution of benign group showed small branch blood flow, regular formation and lowresistant spectrum, and the distribution of malignant group showed malposition, deformation disorder and high-resistant spectrum. Conclusion Color Doppler ultrasonography has value for differential diagnosis of benign and malignant lymphadenectasis on cervix. It can be the method of first choice.
