Clinical application of CT-guided fine-needle percutaneous biopsy to the diagnosis of lung lesions

Objective:To evaluate the value of CT-guided fine-needle percutaneous biopsy in diagnosing patients with the lung lesions.Methods:Aspiration biopsy was performed in 120 patients with 7#～9# puncture needle and Bard biopsy needle guided and located by CT.Results:Cytological and histological materials were available in 84 (70%)cases for successful diagnosis of lung cancer.Sensitivity of cytological examination amounted to 72.6%(61/84) and that of histological examination 80.9%(68/84);sensitivity of biopsy were 93.3% ,and specificity of biopsy were 100%.The diagnosis rate was 97.5%.Complications occurred in 8 cases(6.7%),including 5 cases of pneumothorax and 3 cases of hemoptysis.Conclusion:CT-guided fine-needle percutaneous biopsy is a successful,efficient and safe diagnotic method with accuracy and few complications,which can provide evidence for clinical diagnosis and should be recommended for wider use.
