摘　　要：目的探讨影响CT引导肺穿刺活检诊断准确率的因素。方法回顾性分析CT引导肺部病变穿刺活检264例,对穿刺活检术的诊断正确率与病灶的大小、位置、进针深度进行Logistic回归分析,并分析并发症发生情况。结果CT引导肺穿刺活检诊断正确率分别为87.5%,气胸及病灶周围出血的发生率均为1.9%。Logistic回归发现,病灶的大小是影响穿刺活检正确率的主要因素(Wald=12.891,P=0.00034,OR=0.96)。结论CT引导肺穿刺活检灶诊断准确率均较高,病灶的大小影响穿刺活检的正确率。Objective To evaluate the factors which may affect the diagnostic accruracy of CT-guided percutaneous transthoracic lung biopsy for pulmonary lesions. Methods CT-guided percutaneous transthoracic lung biopsy was performed in 264 patients, all of which were proved by surgical pathology or clinical follow-up. A logistic regression analysis was used to investigate the relationship between the location and the size of the lesions and insertion depth of biopsy needles and the diagnostic accuracy of CT-guided percutaneous transthomcic lung biopsy. The complication rate including pneumatothorax and bleeding rate were record. Results The diagnostic accuracy was 87.5%.Both the pneumothorax and the bleeding of lesion were 1.9%. The size of lesion was suggested by Logistic regression analysis had a significant influence on the diagnostic accuracy （Wald=12.891,P=0.00034, OR=0.96）. Conclusion CT-guided pereumneous transthoracic lung biopsy has a high diagnostic accuracy for pulmonary lesions. The size of the lesions had significant effect on the diagnostic accuracy.
