Official Title: Effects of Bronchodilation on CT Parameters Reflecting Airways Remodelling, and Pulmonary Emphysema Extent: Comparisons Between CT Scans Obtained Before and After Bronchod
Brief Summary:
CT studies considering bronchial dimensions in chronic obstructive pulmonary disease (COPD) were conducted without control of bronchodilation. Some data however suggest that total lung capacity (CT scan is performed after full inspiration) is increased in individuals affected by chronic or spontaneous bronchoconstriction and may decrease after bronchodilatation. Furthermore, no study has assessed the effect of bronchodilation on CT scans parameters reflecting airway remodelling and emphysema extent in COPD patients.
This is a prospective study whose purpose is to assess the effect of bronchodilation on lung CT scan and pulmonary function testing (PFT) in COPD patients.
