摘要
目的:观察浅表淋巴结(主要包括颈部、腋窝下及腹股沟区淋巴结)病变超声声像图特征及其形成的病理基础,以探讨超声在淋巴结疾病中的诊断价值。方法:216例患者的480个病变浅表淋巴结行超声及病理检查,并选取80例作为对照组,分析二维声像图及彩色血液改变,并结合病理检查结果,对不同病因的浅表淋巴结病变进行分析。结果:正常组及良性组淋巴结长径/横径(L/T)≥2,收缩期峰值血流速度(Vmax)≤15cm/s,RI≤0.6;恶性组L/T<2,Vmax>25cm/s,RI>0.8;结核组L/T<2,RI≤0.62,并可见融合征象。结论:超声是诊断浅表淋巴结病变的首先影像学诊断方法。
Objective： To investigate the relationship between the ultrasonographic and pathologic changes of superficial lymphnode,and to determine the diagnostic value of ultrasonography in lymph node diseases.Methods： Eighty normal persons and 216 patents with different superficial lymph node diseases were divided in to 4groups（normal,benign,tuberculosis and malignant node group）according to the biopsy of lymph node. Two-dimenfional ultrasound and color doppler flow imaging（CDFI） were performed in an 4 group. Lengh（L） and transverse dliameter（T） of every node, maximal velocity （Vmax） and resistance index（P,I） of their supplying arteries were measured. Results： （Vmax）≤15cm/s and RI≤0.6; in benign and normal groups. L/T 〈 2, Vmax 〉 25cm/s and RI 〉 0.8 in malignant group, while L/T 〈 2 and RI≤ 0.62 in tuberculosis group, combining sign could be found in tuberculosis and malignant group. Conclusions： Ultrasonography is valuable for the evaluation tion in various lymph node diseases.
