CT of the cranium in head injury.

Computed tomography (CT) allows fast, accurate diagnosis of intracranial bleeding so that the role of cerebral angiography in acute trauma is now quite limited. Management of the patient with multiple injuries including head injury may differ from that of patients with head injury alone. Several different intracranial abnormalities may occur immediately after injury and during the following few days, including intracranial bleeding and edema. CT is of great help in following the clinical course of such patients.
