中文摘要：

目的：探讨带引导针活检枪在 CT 引导下经皮穿刺肺活检对肺部肿块、弥漫性病变、实质性病灶等病变的诊断价值及并发症的防治。方法：回顾性分析我科52例（B 组）带引导针活检枪 CT 引导下经皮穿刺肺活检和32例（A组）不带引导针的活检枪 CT 引导下经皮穿刺肺活检相关资料。结果：B 组52例患者中有50例取得阳性结果，确诊率为96．2％，并发症发生率为23．1％；A 组32例患者中有29例获得阳性结果，确诊率为90．6％，并发症发生率为43．8％。结论：带引导针活检枪 CT 引导下经皮肺活检具有定位准确、活检阳性率高、并发症少、安全性高等优势，对肺部肿块、弥漫性病变、实质性病灶等病变的诊断价值高于不带引导针的活检针 CT 引导下经皮穿刺肺活检，可广泛应用于具有穿刺适应证的肺部疾病患者。

英文摘要：

Objective ：To explore the diagnostic value and the prevention of complications for pulmonary mass ,diffuse lesions and parenchymal lesions by percutaneous lung biopsy under CT with guided needle biopsy gun .Methods ：To an‐alyze retrospectively the related data in my department about 52 cases （group B）by percutaneous lung biopsy under CT with guided needle biopsy and 32 cases （group A）by percutaneous lung biopsy under CT without guided needle biopsy . Results ：In group B 50 patients demonstrate positive result ,the positive rate is 96 .2% ,and the complication rate is 23.1% ;in group A 29 patients demonstrate positive result ,the positive rate is 90 .6% ,and the complication rate is 43.8% .Conclusion ：Percutaneous lung biopsy under CT with guided needle biopsy gun is characterized by its advanta ‐ges of accurate positioning ,high positive rate of biopsy and low complications with high diagnostic value for pulmonary mass ,diffuse lesions and parenchymal lesions ,and it can be applied widely for lung disease patients comfortable with percutaneous treatment .
