【ed】：Purpose：Meta analysis was used to analyze the value of real-time ultrasonic elastography in differentiating benign and malignant cervical lymph nodes. Materials and Methods：Computer search pubmed,embase,cochrane, Wanfang,CNKI, Vip, CBM,the retrieval languages are English and Chinese,Search date to February 28, 2019.The published literatures on the differential diagnosis of cervical lymph node benign and malignant by real-time ultrasonic elastography were collected, and the literatures using ultrasonic elastic score as diagnostic criteria were selected as the included literature, and all the included literatures were examined for heterogeneity. The (quadas) scale was used to evaluate the diagnostic accuracy recommended by cochrane Collaborative Network.Combined sensitivity.Combined sensitivity, concomitant specificity, positive likelihood ratio and negative likelihood ratio were used. The accuracy of real-time ultrasonic elastography in differential diagnosis of cervical lymph nodes was evaluated by calculating the diagnostic ratio and the area (AUC) under the curve of the receiver operating characteristic curve (SROC curve).Results：A total of 11 articles were included, including 8
