Overview

Head CT scan is the first and foremost test in evaluation of traumatic brain injury.

CT

• The CT test of choice in traumatic brain injury is a non-contrast CT head. The test is fast, inexpensive and widely available.
• It plays a crucial role in the diagnostic workup, classification, prognosis and workup.
• Acute findings of CT head include
  • Midline shift
  • Cerebral contusion
  • Brain herniation
  • Hydrocephalus
  • Skull fracture
  • Hematomas
  • Subarachnoid hemorrhage
  • Intraventricular hemorrhage
