'''Chronic obstructive pulmonary disease''' (COPD) is characterised by persistent respiratory symptoms and airflow limitation due to airway and/or alveolar abnormalities. It’s common, preventable, and treatable. It is defined as a post-bronchodilator [[FEV1/FVC ratio]] of < 0,70. | <section begin="radiology" />'''Chronic obstructive pulmonary disease''' (COPD) is characterised by persistent respiratory symptoms and airflow limitation due to airway and/or alveolar abnormalities.

Prevalence is expected to rise, and it’s expected to be the leading cause of death in 15 years. | It affects 11,7% of the world and it’s the third leading cause of death worldwide.

The bronchodilator test is performed to distinguish COPD from bronchial asthma. If the FEV1 improves more than 12% after bronchodilator, bronchial asthma is diagnosed. | The bronchodilator test is performed to distinguish COPD from bronchial asthma.

=== Imaging === | |||
Imaging is not necessary for the diagnosis of COPD. In case of emphysema, [[chest radiography]] will show hyperinflation of the lungs, as evidenced by horizontal ribs, widened intercostal space, increased anterioposterior diameter (seen on the lateral view), flattened diaphragm, and increased transparency of the lung.<section end="radiology" /> | |||
