Overview

A high-resolution computed tomography scan of the chest may show the distribution of emphysema throughout the lungs and can also be useful to exclude other lung diseases.

CT scan

• High-resolution CT scan is more sensitive and specific than standard chest Xray.

• Outlined bullae are better visualized on CT scan than CXray.

• HRCT may help in diagnosing other COPD for instance alpha antitrypsin deficiency shows lower lobe involvement on HRCT

• Helps in decision making regarding treatment
