Objective To evaluate the clinical application of 64-row CT-guided percutaneous transthoracic needle automatic aspiration biopsy on diagnosing lung lesions under 64-row CT-Guidance. Methods Retrospectly studied on 55 patients undergoing CT-guided percutaneous transthoracic needle aspiration biopsy under 64-row CT-Guidance,53 of them were diagnosed hy pathology. Results Among these 55 patients,39 cases were proved malignant lung cancer, and among these 39 cases, 17 cases were squamous cell carcinoma , 21 cases were adenomatous carcinoma ,1 case was anaplastic carcinoma,6 cases of 55 patients were metastatic lung cancer , 2cases were pleural mesothelioma ,5 cases were inflammatory lesions ,1 case was pulmonary tuberculosis and 2 cases couldn't be diagnosed. The diagnostic accuracy was 96％ ,and there was no serious complications. Conclusion percutaneous transthoracic needle automatic aspiration hiopsy under 64-row CT-Cuidance was a safe and accurate method in the diagnosing and differential diagnosing lung lesions , which had high clinical value.%目的探讨64排CT引导下全自动活检枪经皮穿刺活检肺内病灶在临床中的应用.方法回顾性分析55例经皮穿刺肺内病灶的患者,经病理明确诊断53例.结果 55例患者穿刺诊断为原发性肺癌39例(其中鳞癌17例、腺癌21例、未分化癌1例),转移性肺癌6例,胸膜间皮瘤2例,结核1例,炎性病变5例,不能明确诊断2例.穿刺活检诊断准确率为96.4%,均未出现危及生命的严重并发症.结论 64排CT引导下全自动活检枪经皮肺穿刺活检是一种安全、准确的诊断和鉴别诊断肺内病变的方法,具有较高的临床应用价值.
