Diagnostic Performance of the Modified Lung-RADS in a Tuberculosis-endemic Country: The Korean National Lung Cancer Screening Program.
Chest
January 2025
Division of Cancer Early Detection, National Cancer Control Institute, National Cancer Center, 323 Ilsan-ro, Ilsandong-gu, Goyang 10408, Korea. Electronic address:
Background: In 2019, Korea initiated the world's first national low-dose computed tomography (CT) lung cancer screening (LCS) program, adapting the Lung CT Screening Reporting and Data System (Lung-RADS) to counteract the high false-positive rates driven by prevalent tuberculosis.
Research Question: Does the modified Lung-RADS enhance screening specificity while maintaining sensitivity?
Study Design And Methods: This nationwide, retrospective, cohort study included high-risk current smokers aged 54 to 74 with at least 30 pack-years, participating in the national LCS program from 2019 to 2020. The modified Lung-RADS 1.
Diagnostic accuracy of ultra-low-dose chest CT vs chest X-ray for acute non-traumatic pulmonary diseases.
Eur Radiol
January 2025
Department of Radiology and Nuclear Medicine, Amsterdam UMC, University of Amsterdam, Amsterdam, The Netherlands.
Objectives: To compare the diagnostic accuracy of ULDCT to CXR for detecting non-traumatic pulmonary diseases at the emergency department (ED) and to study diagnostic confidence levels.
Methods: Secondary analysis of the prospective OPTIMACT trial (2418 ED participants randomly allocated to ULDCT or CXR). Diagnoses at imaging at the ED were compared to the reference diagnosis on day 28.
Budget impact of low-dose computed tomography screening for lung cancer in Argentina.

Department of Health Technology Assessment and Health Economics, Institute for Clinical Effectiveness and Health Policy (IECS), Buenos Aires, Argentina.
Background: Lung cancer (LC) is a leading cause of cancer mortality in Argentina. Low-dose computed tomography (LDCT) had demonstrated higher efficacy than chest radiography as a screening method for early detection and reducing LC mortality. This study estimates the Budget Impact of implementing annual LDCT screening for individuals aged 55-74 with at least 30 pack-years of smoking in Argentina.

Radiology Department, the First Affiliated Hospital of Jinzhou Medical University, Jinzhou, China (J.Z., F.X., Q.S., J.T., S.W., X.L.). Electronic address:
Rationale And Objectives: Severe COVID-19 typically results in pulmonary sequelae. However, current research lacks clarity on the differences in these sequelae among various clinical subtypes. This study aimed to evaluate the changing lung imaging features and predictive factors in patients with COVID-19 pneumonia in northern China over a 12-month follow-up period after the relaxation of COVID-19 restrictions in 2022.
