Abstract:

To explore the clinical value of mediastinal needle biopsy under CT guidance. ［Methods］ CT-guided percutaneous biopsy were performed in 25 mediastinal lesions with automated cutting needle. Bioptic samples were examined in histology and cytology simultaneously. ［Results］ The accuracy of puncture was 96% (24/25); diagnostic accuracy was 95.8% (23/24) in cytologic study and 87% in histologic examination. The overall diagnostic accuracy was 92% (23/25). The incidence of pneumothorax was 24% (6/25), no one was needed to treat with drainage. 3 cases were observed lung hemorrhage ; hemoptysis occurred in only one (4%) of the patients, follow-up was needed. ［Conclusion］ Mediastinal needle biopsy under CT guidance is a safe and effective procedure towards the diagnosis of mediastinal masses
