多层螺旋CT引导下穿刺对孤立性肺结节的诊断价值

目的：探讨MSCT引导下穿刺孤立性肺结节应用价值.方法：经MSCT检查56例孤立性肺结节,穿刺经病理或随访证实,分析MSCT的敏感性、特异性、准确性及并发症.结果：56例中肺癌38例,假阴性4例,肺部良性结节14例无假阳性;对恶性结节敏感性90%、准确性92%、特异性100%,良性结节阴性预测值78%.一次穿刺成功率高,气胸发生率16%.结论：MSCT引导下穿刺孤立性肺结节准确性高而并发症较低,可作为鉴别结节良恶性的首选方法之一,对确定临床诊断及指导治疗具有重要的价值.

The clinical value of MSCT guided needl biopsy in peripheral solitary pulmonary lesions and its clinical value

Objective: To evlauate of value of MSCT guided needling biopsy in the diagnosis of peripheral solitary pulmonary lesions. Methods: MSCT guided needling was performed in 56 cases with peripheral solitary pulmonary lesions and diagnosis were confirmed dinically and hstologically. Results: There were 38 lung cancer paients in this study.False diagnosis was found in 4 cases.There were 14 benign nodules in which diagnosis were all accurate. The benign diagnostic accuracy was 100% and the lung cancer diagnostuic accuracy was 90.5% and the total accuracy was 92.9%. The ratio of penumothorax was 16%. Conclusion: MSCT guided needling biopsy can play a significant role in the clinical dingnosis of perpheral solitary pulmonary lesions, it is one of the most accurate means in qualitative analysis with less complication.
