Updates in Lung CT Screening Reporting and Data System (Lung-RADS)

Abstract

Lung cancer is the principal cause of cancer-related mortality worldwide. There is global growing interest in lung cancer screening (LCS) using low-dose computed tomography (LDCT) to help early detection of lung cancer and decrease mortality rates. In 2014, the American College of Radiology (ACR) introduced Lung CT Screening Reporting and Data System (Lung-RADS) version 1.0, a standardized reporting system for managing lung nodules detected on LCS LDCT. The updated versions, Lung-RADS 1.1 and 2.0, were introduced in 2019 and 2022, respectively, to incorporate new knowledge about lung nodules’ behavior and align with current LCS criteria. This review aims to provide a comprehensive overview of the changes made in these updated versions and highlight their implications for clinical practice.
