摘　　要：目的:探讨肺部小病灶CT引导下经皮穿刺活检技术的临床应用价值。材料和方法:运用半自动活检针对35例患者肺部小于3cm小病灶的CT穿刺活检结果与手术病理或临床随访情况对照,进行回顾性分析。结果:35例患者共40个小病灶,其中22例为肺癌,6例为肺结核,7例为炎性结节,活检对恶性病变的检出率为84%,无假阳性。结核患者活检诊断准确率为80%。并发症的发生率为31.4%。结论:肺部小病灶的CT引导下经皮穿刺活检准确性较高,穿刺技术中较关键的因素是训练患者的呼吸配合以及操作者的熟练程度。Objective To evaluate the clinical application of CT-guided percutaneous biopsy of small lung lesions. Materials and Methods Thirty five patients of lung lesions smaller than 3cm in diameter underwent CT-guided percutaneous biopsy using automatic cutting needle. The results of biopsy were compared with surgical pathology and clinical follow up. Results Forty small lesions of 35 patients included 22 cases of lung cancer 6 cases of tuberculosis 7 cases of inflammatory pseudotumor CT-guided biopsy detected 84% of cases with lung cancer correctly. There were no false positive cases. Conclusion CT-guided percutaneous biopsy of small lung lesions has a high accuracy. It is important to make the patients cooperate well and improve the doctor’s operating skill.
