Abstract
Tobacco smoke is a well-known risk factor for respiratory diseases such as chronic bronchitis, emphysema, and respiratory bronchiolitis-associated interstitial lung disease (RB-ILD). This study examines the correlation between smoking habits, lung markings on chest radiographs, and CT scan findings, employing the International Labour Organization (ILO) classification for quantification. A prospective cohort of 170 smokers was analyzed, assessing bronchial wall thickening, intralobular opacities, and emphysema severity. Findings indicated a strong association between smoking and increased lung markings, bronchial wall thickening, and centrilobular emphysema. However, interpretation bias and a lack of histological validation are study limitations. Despite these constraints, CT imaging proved effective in detecting emphysema and airway disease. Given the significant correlation between tobacco consumption and radiographic abnormalities, further research is needed to enhance early detection of smoking-induced lung changes.
