高频彩色多普勒超声对颈部肿大淋巴结的再认识

目的:分析颈部肿大淋巴结的高频、彩色多普勒声像图特点。方法:对135例因颈部淋巴结肿大就诊的患者,采用灰阶结合彩色多普勒超声高频探头观察肿大淋巴结的长径/短径(L/S)值、形态、内部结构及CDFI特征。结果:各种不同病因所致的颈部淋巴结肿大各有其超声特征。非特异性反应性淋巴结肿大34例,急性淋巴结炎26例,结核性淋巴结肿大20例,恶性淋巴瘤19例,转移性淋巴结肿大36例。结论:灰阶超声结合彩色多普勒超声明显提高了颈部淋巴结肿大的检出率及检查质量,在一定程度上可以作出定性的诊断。

Recognition Again:Cervical Lymph Nodes Enlargement by Ultrasound

Objective To analyze the value of high frequency and colorultrasonography in diagnosing cervical lymph nodes enlargement.Methods The L/S ratio,shape,interior structure,CDFI spectrum feature of cervical lymph nodes enlargement in 135 patients'nodes were studied with gray scale display and color Doppler ultrasound.Results All kinds of cervical lymph nodes enlargement take on all kinds of characters.Nonspecific lymphadenectasis thirty-four,acte lymphadenitis twenty-six,evil twenty,malignant lymphoma nineteen,transitivity lymphadenectasis thirty-six.Conclusion Gray scale display and color doppler flow imaging can improve detectable rate and check(up)quality.To a certain extent,qualitative diagnosis can be made.
