摘　　要：目的探讨超声造影在反应增生性淋巴结与转移性淋巴结疾病诊断中的价值。方法应用超声造影技术观察17例患者共35个浅表淋巴结的微血管分布,其中反应增生性淋巴结15个(良性组),转移性淋巴结20个(恶性组),对比分析两组超声造影特征。结果超声诊断浅表淋巴结良恶性的敏感性为75%,特异性为73%,准确性为74%;超声造影诊断浅表淋巴结良恶性的敏感性90%,特异性87%,准确性89%。超声造影纠正了二维和彩色多普勒超声检查诊断的2个假阳性和3个假阴性病灶。与常规超声技术比较,超声造影对良恶性淋巴结诊断的准确性显著提高,差异有统计学意义(P<0.05)。结论超声造影有助于鉴别良恶性浅表淋巴结疾病。Objective To evaluate the value of contrast-enhanced ultrasound in the differential diagnosis of superficial lymphadenopathy. Methods Thirty-five lymph nodes from 17 patients were studied both by conventional techniques and contrast-enhanced ultrasound. Of the lymph nodes examined, 15 of them were benign and 20 of them were malignant.The characteristics of enhanced echogenicity of them were comparatively analyzed. Results The sensitivity, specificity, and accuracy of differential diagnosis between benign and malignant superficial lymph nodes by conventional and contrast enhanced ultrasonography were 75%, 73% and 74% versus 90%, 87% and 89%.The diagnostic accuracy was significantly improved by contrast-enhanced ultrasonograhpy compared to conventional ultrasound. Conclusion Contrast enhanced ultrasonography provides valuable evidence for the differential diagnosis of superficial lymphadenopathy.
