[Ultrasound-guided percutaneous needle biopsy in diseases of the chest].

This paper presents the results of ultrasonically guided percutaneous fine needle biopsy in 85 cases with suspected space-occupying lesions of the lung, pleura and mediastinum. The results was positive in 97.6% (83/85), and the accurate diagnostic rate 98.8% (82/83). The incidence of pneumothorax was only 2.4%. The authors believe that this method has the advantages of being simple and easy in operation with high diagnostic rate and few complications.
