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 nodes 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.
