Brief Summary

Chronic obstructive pulmonary disease (COPD) is a common, preventable, and treatable disease that is characterized by respiratory symptoms and airflow limitation that is due to airway and/or alveolar abnormalities usually caused by significant exposure to noxious particles or gases. the CT was used for classification of COPD patients into different phenotypes: phenotype A that has minimal emphysema with or without airway disease, phenotype E that has emphysema without airway disease, and finally phenotype M as a mixed form. The investigators aimed to to identify the phenotypes of COPD using radiologic data obtained by computed tomography. Moreover, this study will be designed to answer the questions about possible correlation between pulmonary function parameters and CT.
