Abstract: Objective To study the value of contrast-enhanced ultrasound in tuberculous cervical lymph node biopsy.Methods Seventy-nine patients with cervical lymph node were divided into two groups.The lymph nodes of group A were used as real-time ultrasound guided biopsy; the lymph nodes of group B were contrast-enhanced ultrasound firstly to determine the target lymph node and the puncture point,then were detected with needle biopsy.Results Group A:for the 23 lymph nodes of 23 patients,the rate of intact tissue was 52.1％ and the positive rate of pathological diagnosis was 73.9％.Group B:for the 56 lymph uodes of 56 patients,the rate of intact tissue was 98.2％ and the positive rate of pathological diagnosis was 100％ (Chi square value was 23.37 and 12.31,P ＜ 0.05).Conclusion The application of contrast-enhanced ultrasound before cervical lymph node biopsy can obviously improve the rate of intact tissue and the positive rate of pathological diagnosis.
