摘　　要：目的探讨超声弹性成像与常规超声检查对颈部肿大淋巴结的诊断价值。方法对37例患者85枚淋巴结分别进行超声弹性成像和常规超声检查。依据弹性成像的5种模式和常规超声的5个评分标准,分别对淋巴结进行良恶性诊断。结果 85枚淋巴结中,反应性增生32枚;转移性53枚。弹性成像诊断的敏感性、特异性与准确性分别为83.00%、90.60%、85.88%;常规超声检查则分别为94.30%、59.40%、81.18%。2种检查方法的准确性尚无统计学差异(χ2=0.41,P>0.05)。结论弹性成像与常规超声检查均有助于颈部淋巴结良恶性的鉴别诊断,2种检查方法联合应用可提高对颈部淋巴结的诊断价值。Objective To explore the diagnostic value of ultrasonic elastography and conventional ultrasonogra- phy in swollen cervical lymph nodes. Methods Eighty-five lymph nodes from 37 patients were examined by both ultrasonic elastography and conventional ultrasonography. According to five patterns of elastography and scores for five criteria of conventional ultrasonography, lymph nodes were diagnosed benign or malignant. Results In eighty-five lymph nodes, there were 3Z reactive and 53 metastatic nodes. Sensitivity, specificity and accuracy of ultrasonic elastography were 83.00%, 90.60%, 85.88%, respectively and 94.30%, 59.40%, 81.18% from conventional ultrasonography. There was no statistical difference in accuracy between ultrasonic elastography and conventional ultrasonography （χ^2 = 0.41, P〉0.05） . Conclusions Elastography and conventional ultrasonography are both helpful in differentiating malignant from benign lymph nodes, and the combination of the above two methods can improve the diagnostic value of cervical lymph nodes.
