原发性肺癌经纤支镜作细胞刷检的诊断率比较高,在此基础上追加透视下针刺活检,可望得到更高的诊断率,但是,由于肺癌病例的增加,有些病灶经纤支镜途径难以到达,且在透视下穿刺难以命中或增加发生危险的机会,对此,我们施行 CT 引导肺穿刺活检(GT-NAB)30例,平均年龄63岁(42～83),男 Primary lung cancer by fiberoptic bronchoscopy for the high rate of cell brushing on this basis, additional fluoroscopy needle biopsy, is expected to get a higher diagnostic rate, however, due to an increase in lung cancer cases, some lesions through the fiber Difficult to reach the bronchoscopic approach, and in the perspective of the puncture is difficult to hit or increase the risk of dangerous opportunities, we performed CT guided lung biopsy (GT-NAB) in 30 cases, mean age 63 years (42 to 83), male
