目的探讨超声弹性成像（ultrasound elastography，UE）对颈部恶性淋巴结鉴别诊断的价值。方法对96例患者的96个肿大淋巴结行二维超声（2DUS）、彩色多普勒血流成像（CDFI）及UE检查，其中UE采用弹性评分法进行评价。以超声引导下穿刺活检的病理检查结果为标准，比较常规超声与UE对颈部良、恶性淋巴结鉴别诊断的价值。结果淤常规超声诊断颈部恶性淋巴结的敏感度、特异度、准确率、阳性预测值及阴性预测值分别为76.6%、81.3%、78.1%、89.1%及63.4%；UE诊断颈部恶性淋巴结的敏感度、特异度、准确率、阳性预测值及阴性预测值分别为90.6%、81.3%、87.5%、90.6%及81.3%。于UE诊断颈部恶性淋巴结的准确率高于常规超声，差异有统计学意义（字2=13.304，P约0.001）；常规超声、UE与病理检查结果的吻合系数分别为0.540（P约0.001）、0.719（P约0.001），UE与病理检查结果的吻合度高于常规超声。结论超声弹性成像技术对颈部恶性淋巴结的鉴别诊断具有一定的应用价值。
目的探討超聲彈性成像（ultrasound elastography，UE）對頸部噁性淋巴結鑒彆診斷的價值。方法對96例患者的96箇腫大淋巴結行二維超聲（2DUS）、綵色多普勒血流成像（CDFI）及UE檢查，其中UE採用彈性評分法進行評價。以超聲引導下穿刺活檢的病理檢查結果為標準，比較常規超聲與UE對頸部良、噁性淋巴結鑒彆診斷的價值。結果淤常規超聲診斷頸部噁性淋巴結的敏感度、特異度、準確率、暘性預測值及陰性預測值分彆為76.6%、81.3%、78.1%、89.1%及63.4%；UE診斷頸部噁性淋巴結的敏感度、特異度、準確率、暘性預測值及陰性預測值分彆為90.6%、81.3%、87.5%、90.6%及81.3%。于UE診斷頸部噁性淋巴結的準確率高于常規超聲，差異有統計學意義（字2=13.304，P約0.001）；常規超聲、UE與病理檢查結果的吻閤繫數分彆為0.540（P約0.001）、0.719（P約0.001），UE與病理檢查結果的吻閤度高于常規超聲。結論超聲彈性成像技術對頸部噁性淋巴結的鑒彆診斷具有一定的應用價值。

Objective To assess the diagnostic value of ultrasound elastography(UE)for detecting malignant cervical lymph nodes. Methods A total of 96 patients with cervical lymph nodes were analyzed by UE and by conventional ultrasonography(US)involving two-dimensional ultrasonography and color Doppler flow imaging. An elastic method was used to evaluate the diagnostic value of UE. All malignant lymph nodes were confirmed by pathology,and the diagnostic performance of the two methods was compared. Results The sensitivity,specificity,accuracy,and positive and negative predictive values of US in diagnosing malignant cervical lymph nodes were,respectively,76.6%,81.3%,78.1%,89.1% and 63.4%.The corresponding values for UE were 90.6%,81.3%,87.5%,90.6% and 81.3%.UE showed higher accuracy than US for diagnosing malignant cervical lymph nodes.The diagnostic agreement rate of UE with surgical pathology was 0.540(P≥0.001),compared to 0.719(P≥0.001)for US.UE showed higher diagnostic consistency than US. Conclusion UE may be useful for diagnosing malignant cervical lymph nodes.
