[Acute head trauma: diagnostic imaging]

Abstract

Computed tomography (CT) ist the primary modality of choice for imaging patients with acute head trauma. Lesions of the soft tissues and of the bones can be assessed more precisely than with other imaging modalities. With magnetic resonance imaging (MRI) additional information may be gained especially in subacute and chronic posttraumatic conditions. Urgent indication to perform a CT examination depends on the patient's history and on the mechanism of trauma. Image interpretation has been performed in the context of typical pathologic effects of trauma and with respect to potential therapy.
