Traumatic lesions to the brain are well seen without i.v. contrast agents. In particular, traumatic hemorrhage, be it epidural, subdural, subarachnoid, parenchymal or intraventricular, is spontaneously hyperdense on CT. Theoretically, i.v. contrast would be, at best useless, at worst counterproductive.

Ct scanning protocols for head trauma?

A brain scan after a head trauma is nearly always done without contrast, because bleeding also shows up white on the scan. The scan should be done as quickly as possible with the shortest scan time because patients with head injuries are often restless. If there is a suspected neck injury, the patients head will have be scanned in the position it is in, and the patient can not be moved into the 'head box'. After the scan, both brain and bone setting views should be looked at to establish if there are any fractures.
