Computed tomography
Computed tomography (CT scanning) is a more sensitive test for pulmonary contusion,[1][2] and it can identifyabdominal, chest, or other injuries that accompany the contusion.[3] In one study, chest X-ray detected pulmonary contusions in 16.3% of people with serious blunt trauma, while CT detected them in 31.2% of the same people.[4] Unlike X-ray, CT scanning can detect the contusion almost immediately after the injury.[5] However, in both X-ray and CT a contusion may become more visible over the first 24–48 hours after trauma as bleeding and edema into lung tissues progress.[6] CT scanning also helps determine the size of a contusion, which is useful in determining whether a patient needs mechanical ventilation; a larger volume of contused lung on CT scan is associated with an increased likelihood that ventilation will be needed.[5] CT scans also help differentiate between contusion and pulmonary hematoma, which may be difficult to tell apart otherwise.[7] However, pulmonary contusions that are visible on CT but not chest X-ray are usually not severe enough to affect outcome or treatment.[8]
