Understanding Lung-RADS 1.0: A Case-Based Review

Semin Ultrasound CT MR. 2018 Jun;39(3):260-272. doi: 10.1053/j.sult.2018.03.001. Epub 2018 Mar 8.


Lung cancer is the leading cause of cancer death in both men and women in the United States. The National Lung Screening Trial (NLST) demonstrated that low-dose computed tomography (CT) screening reduces lung cancer mortality by 20% compared to screening with chest radiography. Currently, many institutions in the US are implementing lung cancer screening programs. The use of lung-RADS as a quality assurance tool allows standardization of lung cancer screening CT lexicon, reporting and management recommendations, and reduces confusion in lung cancer screening CT interpretations. Lung-RADS will also facilitate outcome monitoring and future auditing of lung cancer screening programs, assist research, and consequently refine and improve lung cancer screening practices. Familiarity with lung-RADS version 1.0 is essential not only for radiologists interpreting low-dose computed tomography screening studies, but all medical personnel involved in multidisciplinary lung cancer screening programs. This article reviews the Lung-RADS categories and management recommendations using a case-based approach.
