Role of MDCT in The Evaluation of Smoking-Related Lung Diseases

Abstract Background: Chronic smoking is a major risk factor for chronic obstructive pulmonary disease (COPD), interstitial lung diseases (ILDs), and lung malignancies. MDCT with HRCT technique plays a key role in detecting and characterizing these conditions. Aim: To evaluate the role of MDCT in assessing smoking-related lung diseases. Materials and Methods: A hospital-based observational study was conducted among 100 chronic smokers. HRCT images were evaluated for airway and parenchymal abnormalities. Results & Discussion: Centrilobular lucencies (43%), bronchial wall thickening (34%), and hyperinflation (27%) were the most common findings. COPD was diagnosed in 49% of cases, while ILDs and suspicious neoplastic lesions were identified in the remaining patients. Conclusion: MDCT is a sensitive imaging modality for detecting and characterizing smoking-related lung diseases.
