The use of the CAT scanner in the management of patients with head injury transferred to the regional neurosurgical unit.

The use of computerized tomography (CAT scanning) in the management of 204 severely head-injured patients transferred to a regional neurosurgical unit has been evaluated. The experiences gained with CAT scan have been contrasted with those of a period immediately before when the CAT scan was not available. The CAT scan has resulted in a major reduction in burr-holes without worsening the long-term result.
