Objective To explore the diagnostic value of CT-guided percutaneous transthoracic needle biopsy in patients with pneumonic diseases and the factors influencing its accuracy. Methods CT-guided percutaneous transthoracic needle biopsy using an 18-gauge Chiba needle was carried out in 412 consecutive patients with pneumonic diseases dated from May 2002 to October 2003,followed by pathological examinations, the accuracy was analyzed in all cases. Results 334 out of 412 cases were proved to be malign either by surgery or follow up or clinical examinations, among which 313 cases were confirmed by needle biopsy. It was verified that the rate of correct diagnosis for the malign pathological was 93.7% (313/334). 21 cases (6.3%) were false negative, while false positive was not found.56 cases were proved to be benign.It was verified that the rate of correct diagnosis for the benign was 71.8%(56/78).Peumothorax occurred in 19 patients. Conclusion CT-guided percutaneous needle biopsy in pneumonic diseases is a safe and effective diagnostic means,which has a high diagnostic rate and few complications. Its accuracy relates to the size of the target lesion.
