CT引导下肺部穿刺活检的应用分析

Application and Analysis of CT-Guided Needle Biopsyof Lung

本文目的是分析和评价CT引导下肺部穿刺活检中体位的选择、穿刺点定位穿刺针及穿刺方式等因素对本项检查结果的影响。所用材料与方法：回顾性分析36例资料完整的病例，分别统计了切割法和抽吸法的阳性率、假阳性率、假阴性率、气胸率及局部出血发生率和组织学诊断率。得到结论为切割法较抽吸法能获得更高的阳性率和组织学诊断率，但局部少量出血发生率略高；穿刺针在小于16G范围内，两种穿刺方法的气胸发生率无明显差异。另外，操作者的熟练程度、穿刺部位、穿刺点定位、穿刺针的选择以及对标本的处理，病理科技术员和病理科医师的水平均直接影响到穿刺结果的正确率。

Purpose: To analyses and evaluate such the factors as body position. ponitgot in, the type of needele and how to deal with sample, et al, which influence theresults of CT Guided needle biopsy of the lung. Materials and methods: To comparethe cutting method with the needle aspiration on the positive rate false positiverate, negative rate, false negative rate and the complication of air-chest and localbleeding in 36 cases, Conclusion cutting biopsy can get higher positive rate andhistologic diagnosis then needle aspiration, but more local small bleeding. Usingthe needle smaller 16 G the rate of air-chest is undifferentiated with the two methodsof biopsy. Such factors as the operate technique, body position, the point got in , thetype of the needle, how to deal with the sample, the level of pathologist are directlyconnected with the result.
