目的:通过对浅表淋巴结病变的研究,提高彩色多普勒超声对良恶性淋巴结鉴别诊断价值。方法:观察并记录浅表肿大淋巴结长径与横径比、血流形态、动脉最大流速和阻力指数等。结果:87个淋巴结中,炎症15个,反应性增生22个,淋巴瘤16个,转移瘤34个。结论:高频率、高分辨率的彩色多普勒超声有助于良恶性淋巴结的鉴别,为临床提供有力的诊断依据。 OBJECTIVE: To improve the differential diagnosis of benign and malignant lymph nodes by color Doppler sonography through the study of superficial lymph node lesions. Methods: The long and narrow superficial lymph nodes were observed and recorded. The shape of blood flow, the maximum velocity of artery and resistance index were observed and recorded. Results: Of 87 lymph nodes, 15 were inflammatory, 22 were hyperplastic, 16 were lymphoma and 34 were metastatic tumors. Conclusion: High-frequency, high-resolution color Doppler ultrasound is helpful to differentiate benign and malignant lymph nodes and provide a powerful diagnostic basis for clinical practice.
