Chest computed tomography (CT) is extremely useful in the assessment of injuries to the aorta, chest wall, lung parenchyma, airway, pleura, and diaphragm. It is very useful in estimating the extent of contusion, which is important in predicting the degree of posttraumatic respiratory insufficiency. The sensitivity of CT in detecting pulmonary contusions is very high. Pneumothorax succeeds rib fractures as the second most common injury seen in chest trauma. CT is able to detect pneumothoraces missed by initial chest radiograph in 5% to 15% of trauma patients. Empyemas are exudates associated with pulmonary infections. On CT, they usually have a regularly shaped lumen and a smooth inner surface. Traumatic rupture of the aorta (TRA) is rarely visualized on CT because patients expire from exsanguination before reaching medical facilities. Posterior dislocations are more easily diagnosed on CT. Scapular fractures are frequently overlooked on the interpretation of chest radiographs.
