高频彩超检查390例颈部淋巴结肿大结果分析

目的总结高频彩超检查在颈部淋巴结定性诊断中的临床意义。方法对390例彩超检查结果与细胞学、病理学诊断进行对照，比较正常、良性、恶性淋巴结的高频彩超特点。结果肿大淋巴结和正常淋巴结的形态、结构方面存在很大差异，不同性质的淋巴结纵横径比值差异均有统计学意义（P〈0．05）。反应性淋巴结和结核性肿大淋巴结内髓质增宽、回声增强，皮质变窄，恶性肿大淋巴结内髓质变薄受压偏心，皮质增厚，回声低弱不均匀。反应性淋巴结和结核性肿大淋巴结内血流丰富、呈树枝状分布规则；而恶性肿大淋巴结内血流呈不规则紊乱的血流信号。结论高频彩超对及时发现颈部肿大的淋巴结，正确区分病变的性质具有重要临床意义。

Analysis of results of high frequency color doppler ultrasound in the diagnosis of 390 cases of cervical lymph node enlargement

Objective To summarize the clinical significance of high - frequency color doppler ultrasound in the diagnosis of cervical lymph node enlargement. Methods The features of the normal, benign and malignant lymph nodes were studied by high frequency ultrasound imaging. Results There were differences in morphology and structure between the swollen lymph nodes and normal lymph nodes. The quotas of the L/S ratio in lymph nodes with different properties were significantly different （ P 〈 0. 05 ）. Interios echo of reactive hyperplastic lymphadenitis and tuberculous enlargement of neck lymph nodes displayed wide and brighter medulla and narrow cortices, but the malignant enlargement of lymph nodes were on the contrary. CDFI Showed the blood flow of the most benign enlargement of lymph nodes were more abundant and regular, and the blood flow of most malignant lymph nodes were disorder and irregular. Conclusions High frequency ultrasound examination was valuable for diagosis of neck lymph nodes, especially in indentifying benign or malignant lymph nodes enlargement.
