Lung CT Screening Reporting & Data System (Lung-RADS) 


Lung-RADS® is a quality assurance tool designed to standardize lung cancer screening CT reporting and management recommendations, reduce confusion in lung cancer screening CT interpretations, and facilitate outcome monitoring.


A complete lexicon and atlas will be developed. The atlas will include a description of a medical audit and outcome monitoring process. The lexicon of lung cancer screening CT terms and the reporting format will standardize the language used reports.

The Lung-RADS Assessment Categories document below contains version 1.1 of Lung-RADS, including the assessment categories and management recommendations.
