摘　　要：目的探讨C臂CT在肺小结节(直径≤3 cm)经皮肺穿刺活检中的应用价值。方法 2010年9月-2012年3月在C臂CT引导下行经皮肺穿刺活检的肺小结节55例,病灶直径1.0～3.0 cm。术前、术中及术后均行C臂CT扫描。结果 C臂CT引导下经皮肺穿刺活检病理诊断灵敏度86.8%(33/38),特异度100%,无假阳性病例,假阴性率13.2%(5/38);气胸11例(20.0%),2例行闭式引流术;咯血2例(3.6%),无需特殊处理而自愈。结论 C臂CT引导肺结节(≤3 cm)经皮肺穿刺活检术定位准确,能提高肺小结节穿刺阳性率,及时发现术后并发症,是值得推广的一种影像新技术。Objective To assess the value of C-arm CT scanning in performing percutaneous needle biopsy of pulmonary nodules. Methods During the period from Sep. 2010 to March 2012, a total of 55 patients with pulmonary nodules（1 - 3 cm in diameter） received percutaneous needle biopsy with the help of C- arm CT guidance. C- arm CT scanning was performed before, during and after the procedure. Results The diagnostic sensitivity and specificity of C- arm CT guided percutaneous needle biopsy for pulmonary nodules was 86.84%（33/38） and 100%, respectively. No false-positive case was seen, and the false-negative incidence was 13.16%（5/38）. Pneumothorax due to needle biopsy occurred in 11 cases （20%）, and two cases had to receive thoracic closed drainage. Hemoptysis caused by needle biopsy was seen in 2 cases（3.63%）, and no specific treatment was needed to take. Conclusion C- arm CT guided percutaneous needle biopsy of pulmonary nodules is clinically feasible and safe. This technique ensures that the puncturing needle can be correctly localized, thus the diagnostic accuracy can be improved. Moreover, the postoperative complications can be demonstrated promptly. Therefore, it is worth popularizing this method in clinical practice. （J Intervent Radiol, 2012, 21： 770-772）
