Screening for lung cancer coupled with earlier intervention has long been studied as an approach to mortality reduction. However, minimal progress was achieved until recently, when lowdose spiral computed tomography (LDCT) screening demonstrated a 20% reduction in mortality from lung cancer in a ...

Furthermore, significant dose reduction has been shown not to decrease sensitivity of Lung cancer screening with CT Several feasibility studies of low-dose CT in heavy smokers have been performed. In summary, using similar diagnostic algorithms, they all demonstrated that non-invasive classification of...
The incremental cost-effectiveness ratio ( ICER ) for lung cancer screening with low-dose CT falls below $US100000/ QALY versus no screening, "a threshold level that some experts consider to be a reasonable value in the United States", contend investigators from that country. They compared the...

图5 Results from the reader study—lung cancer screening using current and prior CT volume. 敏感性和特异性分析均采用308例患者的n=308 进行,P值采用双侧置换试验计算,数据随机重采样10000。 六、缺点及展望 (1) 虽然与放射科医生的比较研究比先前发表的研究大,但它们仍然局限于NLST数据集的回顾性数...
With the latest advanced technology, lung cancer screening can be performed with low-dose computed tomography (low-dose CT) with reduced exposure to radiation.
