Objective To investigate the diagnostic value of percutaneous aspiration biopsy of CT-guided mediastinal lymph nodes in patients with bronchial carcinoma. Methods A total of 142 cases of suspected primary lung cancer with mediastinal lymph node enlargement (diameter ≥ 10mm) were randomly selected during the period of 1992 -10 1998-0 9 and 176 needles were made under the supervision of CT scanning. Biopsy and cytology. Results The operative sensitivity (82%) and specificity (100%) were confirmed by operation (98 cases), autopsy (6 cases) and follow-up of 1 year (25 cases). Conclusion CT-guided percutaneous acupuncture for mediastinal lymph node biopsy is a simple and reliable method for the diagnosis and staging of lung cancer.
