Abstract:
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 1 5 3 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.
