"The NLST cannot answer all of the important questions about screening that will be important for implementation," Aberle said.
NLST并不能回答所有有关影像学的重要问题，这有待进一步的研究。
However, the NLST data can be used to develop mathematical models to determine how long screening should be performed and how often.
Aberle说，“然而，NLST取得的数据可以用于建立数学模型，来确定影像学检查所需的最佳时长和频率。
The NLST was designed to answer specific questions about the screening in older heavy smokers and was conducted at sites with sophisticated medical resources and experts.
NLST是为了回答有关老龄重度吸烟者的影像学检查的特殊问题而设计，并且在拥有丰富的医疗资源和专家的站点中进行。
More studies based on the NLST data set are ongoing, and will include reports on the cost effectiveness of spiral ct and the effects of the screening process on smoking behaviors over time.
还有很多基于NLST的数据的研究正在进行，包括有关螺旋ct的成本效用的研究，以及成像过程对长期吸烟习惯的影响的研究。
The NLST is the first trial with sufficient numbers of participants using a randomized design to enable the comparison of mortality differences between spiral CT and chest X-ray, Aberle said.
NLST则是第一次包含大量随机指定的受试者的实验，使得在螺旋CT成像和X射线胸透之间做死亡率的比较成为了可能。
Sponsored by the National cancer Institute, part of the National Institutes of Health, the NLST establishes low-dose spiral CT as the first validated screening test that reduces lung cancer mortality.
NLST由国家癌症研究所(国家健康研究所的一部分)发起，证实了低剂量螺旋CT成像是第一种可以降低肺癌死亡率的扫描检查。
