摘　　要：目的比较肺部影像报告和数据系统（Lung-RADS）与美国国立肺筛查实验（NLST）分类方法在肺部结节筛查中的性能。方法回顾性分析153例进行了基线和基线后筛查的肺部结节患者，分别进行Lung-RADS和NSLT分类，比较2种分类在肺内结节筛查中的敏感度、假阳性率、阳性预测值及阴性预测值。结果153例肺内结节患者在基线筛查中，Lung-RADS与NLST的敏感度、假阳性率、阳性预测值和阴性预测值分别为83．9％、13．2％、6．5％、99．7％和92．5％、26．9％、3．8％、99．8％；在基线后筛查中分别为79．6％、5．5％、11．5％、99．8％和93．5％、22．8％、3．5％、99．9％。结论与NLST分类相比，Lung-RADS分类在基线和基线后筛查均具有较低的假阳性率，减少了肺内低风险结节的筛查。Objective To compare the performance of Lung Imaging Reporting and Date System （Lung-RADS） with National Lung Screening Trail （NLST） in pulmonary nodules screening.Methods 153 patients with pulmonary nodules were analyzed retro- spectively, including, baseline screening and after baseline screening. We compared the sensitivity, false-positive result rate, positive predictive value, and negative predictive value in two methods of screening.Results In baseline screening of all patients with pulmo- nary nodules, the sensitivity, false positive rate and positive predictive value and negative predictive value of Lung-RADS and NLST were 83.9%, 13.2%, 6.5%, 99.7% and 92.5%, 26.9%, 3.8%, 99.8% respectively. In after baseline screening, the sensitivity; false positive rate and positive predictive value and negative predictive value were 79.6%, 5.5%, 11.5%, 99.8% and 93.5%, 22.8%, 3.5%, 99.9% respectively.Conclusion Lung-RADS classification can reduce the false positive rate in screening of pulmonary nod- ules, which reduced the screening of lower risk nodules.
