目的 :探讨超声在浅表淋巴结病良恶性鉴别诊断中的价值。方法 :对113个病人计128个淋巴结的二维超声、彩色多普勒血流显像及脉冲多普勒分析 ,这些结果均经超声引导活检和/或手术病理证实。结果 :淋巴结良恶性的鉴别 ,单项指标(L/T<2,髓质消失 ,RI>0 70)判别 ,其敏感性分别为85 7 % ,43 9%和68 2% ,特异性分别为86 7 % ,93 3%和74 5% ,准确性分别为85 9 % ,55 5 %和68 3%。若三指标联合 ,其诊断恶性淋巴结的敏感性、特异性和准确性分别为38 5% ,96 4 %和70 7 %。结论 :淋巴结各指标联合提高了超声对淋巴结病良恶性的鉴别诊断
Objective : To explore the value of ultrasound in the differential diagnosis of benign and malignant superficial lymphadenopathy. METHODS: Two-dimensional ultrasound, color Doppler flow imaging, and pulsed Doppler analysis were performed on 128 lymph nodes in 113 patients. All of these results were confirmed by ultrasound-guided biopsy and/or pathology. Results: For the differentiation of benign and malignant lymph nodes, individual indexes (L/T<2, disappearance of medulla, RI>0 70) were identified. The sensitivities were 85.7%, 43.9%, and 68.8% respectively, and the specificities were 86. 75%, 93 3% and 745%, respectively, with accuracy of 85 9 %, 55 5 % and 68 3%. If the three indicators are combined, the sensitivity, specificity, and accuracy for diagnosing malignant lymph nodes are 38 5%, 96 4 %, and 70 7 %, respectively. Conclusion : The combination of lymph node indexes improves the differential diagnosis of benign and malignant lymphadenopathy
