Chest X ray can be used as an imaging modality to evaluate the pulmonary impact of COPD. Common findings include visual deformities in the lung sacs.
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.

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

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.
  • CT scan helps in decision making regarding treatment.
