Which chest radiograph finding is commonly associated with COPD?

Air trapping and increased lung volumes are hallmark radiographic clues of COPD, especially in emphysema. When elastic recoil is lost and airways collapse more readily during expiration, the lungs stay overinflated. On a chest X-ray this shows up as lungs that appear unusually large, diaphragms that are flattened and lower, and more space behind the sternum on a lateral view. Vascular markings may look more sparse because the lungs appear hyperlucent with overinflation. These features point to COPD rather than other chest conditions. Pleural effusion would blur the costophrenic angles, pulmonary edema would present with interstitial/alveolar edema and possibly an enlarged heart, and atelectasis would show volume loss with basilar opacities. So hyperinflation best fits COPD.
