摘　　要：目的探讨超声在良恶性肿大淋巴结中的鉴别诊断价值。方法本组89例,应用高频率的彩色多谱勒超声检查肿大淋巴结的形态及内部回声、纵横比(L/T)、彩色多谱勒血流显像(CD FI)及阻力指数(RI)的频谱特征。结果高分辨率和彩色多谱勒超声有助于良恶性淋巴结的鉴别。38例良性肿大淋巴结组中约85%的L/T值>2,测值为2.01±0.22,淋巴结皮质约65%呈向心性增宽,CDFI示血流信号主要存在于淋巴门处,RI为0.63±0.08;36例恶性肿大淋巴结组中约86%的L/T<2,测值为1.46±0.22,淋巴结皮质约69%呈偏心性增宽,CDFI示血流信号多呈不规则的紊乱信号,RI为0.70±0.09。两项指标比较差异均有显著性(P<0.05)。结论彩色多谱勒超声对肿大淋巴结良恶性的鉴别诊断具有较好的应用价值,可作为首选方法。Objective To explore the value of ultrasound identification of the benign lymph node and the malignant superficial tumescent lymph node.Methods The manifestation, internal echo, the L/T ratio, CDFI and RI frequency spectrum feature of the superficial lymph nodes were studied with high frequency and color Doppler ultrasound 89 cases.Results The high rate of distinction and the color Doppler ultrasound were beneficial to distinguish the benign superficial lymph nodes from the malignant.About 85% of the 38 cases of the benign lymph node's L/T ratio was larger than 2 in average(2.01±0.22) and about 65% of the benign lymph node's cortices widened toward the central core. CDFI of the benign lymph nodes showed the signal of the blood flow at the hilum of the node. RI was 0.63±0.08. About 86% of the malignant superficial lymph node's L/T ratio was lower than 2 in average(1.46±0.22), and about 69% of the malignant superficial lymph node's cortices displayed eccontric widening.CDFI of the malignant superficial lymph nodes showed irregular signal of the blood flow, RI was 0.70±0.09.There were significant differences between the two groups(P<0.05).Conclusion Color Doppler ultrasound identification has value for differential diagnosis of benign and malignant lymphadenectasis and can be the mettod of first choice.
