目的 比较研究CT 引导穿刺活检对肺内不同大小结节诊断的应用价值。方法 对96例患者的肺内结节,依大小将大于3cm 的列为大结节,小于3cm 的列为小结节。确诊率通过组织病理学结果评价。并记录肺出血和气胸的发生率。结果 肺内大结节CT 引导穿刺确诊率为91% ,气胸发生率8 % ;肺内小结节CT 引导穿刺确诊率为90 % ,气胸发生率10 % 。结论 CT 引导穿刺活检肺内大结节,小结节确诊率是相同的,两者的并发症同样低
Objective To comparatively study the value of CT guided biopsy in the diagnosis of pulmonary nodules of different sizes. Methods The nodules in the lung of 96 patients were classified as nodules larger than 3 cm in size and nodules smaller than 3 cm. The diagnosis rate was evaluated by histopathological findings. Record the incidence of pulmonary hemorrhage and pneumothorax. Results The diagnosis rate of large pulmonary nodules by CT guided puncture was 91% and pneumothorax was 8%. The diagnosis rate of small pulmonary nodules by CT guided puncture was 90% and the incidence of pneumothorax was 10%. Conclusions CT-guided biopsy of pulmonary nodules, nodules, the diagnosis rate is the same, the two complications are also low
