Background The prognostic value of baseline visual emphysema scoring at low-dose CT (LDCT) in lung cancer screening cohorts is unknown. Purpose To determine whether a single visual emphysema score at LDCT is predictive of 25-year mortality from all causes, chronic obstructive pulmonary disease (COPD), and cardiovascular disease (CVD). Materials and Methods In this prospective cohort study, asymptomatic adults aged 40-85 years with a history of smoking underwent baseline LDCT screening for lung cancer between June 2000 and December 2008.

Introduction: Quantitative computed tomography (qCT) provides detailed spatial assessments of lung structure and function, while electrical impedance tomography (EIT) offers high temporal resolution for analyzing breathing patterns but lacks structural detail. This study investigates the correlation between qCT-based spatial variables and EIT-based temporal signals to elucidate the physiological relationships between these two modalities.
Methods: Six participants with asthma underwent pulmonary function tests (PFTs) before and after bronchodilator inhalation.

Introduction: Interval lung cancers (ILCs) are key indicators of lung cancer screening (LCS) performance. However, data on the proportion, characteristics, and mortality of ILCs under biennial screening in Asian populations remain limited.
Methods: We analyzed participants from the baseline biennial Korean national LCS program between 2019 and 2020.

Background: Radiation-free four-dimensional (4D) dynamic ultrashort echo time MRI (UTE MRI) enables quantification of ventilation defects in chronic obstructive pulmonary disease (COPD) and preserved ratio impaired spirometry (PRISm) populations.
Purpose: To quantify pulmonary ventilation using 4D UTE MRI in PRISm and COPD populations, and determine its ability to distinguish PRISm from non-COPD subjects.
Study Type: Prospective, cross-sectional.
