[摘要] 目的 研究3D重建技术在CT导向下肺部穿刺活检的临床应用。 方法 将40例肺部直径小于3 cm 结节患者按照常规方法和采用Siemens 16层CT 3D 重建技术引导穿刺方法随机分为A组和B组。两组患者均在同一台CT机，同一名穿刺医生和技师配合完成。根据穿刺时间、穿刺针调整次数和并发症等方面对两组结果进行分析。结果 两组患者均在CT的引导下顺利穿刺病灶，B组在穿刺时间、平均调针次数、术后并发症等方面均优于A组。 结论 3D重建技术在CT引导下经皮肺穿刺与常规方法相比，穿刺定位更准确，并发症少，具有较高的临床应用价值。

    [Abstract] Objective To study the clinical application of 3D reconstruction technique in CT-guided needle biopsy of lung. Methods 40 patients with the nodules of diameter less than 3 cm in the lungs were randomly divided into two groups according to the conventional method in group A and needle biopsy guided by Siemens 16-slice CT reconstruction technique in group B.
