Comparison of endobronchial ultrasound and high resolution computed tomography as tools for airway wall imaging in asthma and chronic obstructive pulmonary disease

IntroductionAirway remodeling in asthma and chronic obstructive pulmonary disease (COPD) results in bronchial wall thickening. Bronchial wall thickness (BWT) can be assessed in high-resolution computed tomography (HRCT) and endobronchial ultrasound (EBUS).AimsTo compare BWT measured by EBUS and HRCT in patients with mild-to-moderate asthma and COPD, and to evaluate the relationship between the BWT and pulmonary function.MethodsThe study included...
