This study explored how CT imaging of pulmonary vessels relates to lung function, disease severity, and mortality risk in patients with chronic obstructive pulmonary disease (COPD).
Researchers used automatic software to analyze CT scans from a nationwide cohort, focusing on the features of arterial and venous vessels during breathing.
Findings revealed that certain expiratory vessel characteristics, particularly venous volume, are significant predictors of lung function and mortality in COPD patients.
