Overview
Chest X Ray
Chest X-ray is the most common method used for diagnosis, and may be used to confirm a diagnosis already made using clinical signs.Cohn SM (1997). "Pulmonary contusion: Review of the clinical entity". Journal of Trauma. 42 (5): 973–979. PMID 9191684.</ref> Consolidated areas appear white on an X-ray film.[1] Contusion is not typically restricted by the anatomical boundaries of the lobes or segments of the lung.[2] The X-ray appearance of pulmonary contusion is similar to that of aspiration, and the presence of hemothorax or pneumothorax may obscure the contusion on a radiograph. Signs of contusion that progress after 48 hours post-injury are likely to be actually due to aspiration, pneumonia, or ARDS.
Although chest radiography is an important part of the diagnosis, it is often not sensitive enough to detect the condition early after the injury. In a third of cases, pulmonary contusion is not visible on the first chest radiograph performed.[3] It takes an average of six hours for the characteristic white regions to show up on a chest X-ray, and the contusion may not become apparent for 48 hours.[3] When a pulmonary contusion is apparent in an X-ray, it suggests that the trauma to the chest was severe and that a CT scan might reveal other injuries that were missed with X-ray.[4]
