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.
  • CT scan helps in decision making regarding treatment.
