Computed tomography of acute cerebral trauma.

Hounsfield's development of computed tomography (CT) in 1972 revolutionized the care of patients with acute craniocerebral trauma. CT evaluation facilitates early surgical and medical intervention and has significantly improved patient outcome. This review describes the role of CT in assessing acute head trauma. Despite the growing role of magnetic resonance imaging in the acute, subacute, and chronic phases of brain injury as well as in many other central nervous system disorders, CT retains its unique capacity to image acutely ill patients rapidly and accurately.
