## Overview

[edit | edit source]

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

[edit | edit source]

CT scan in patients with COPD may be helpful in the following aspects.[1]

* 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 1 antitrypsin deficiency shows lower lobe involvement on HRCT.

* CT scan helps in decision making regarding treatment.
