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
- A high-resolution CT scan is more sensitive and specific than standard chest x ray.
- Outlined bullae are better visualized on CT scan than a chest x ray.
- HRCT may help in diagnosing other COPD for instance alpha antitrypsin deficiency shows lower lobe involvement on HRCT
- Helps in decision making regarding treatment
