  • Neuroimaging plays a major role in
    • Delineating the extent of injury
    • Guiding surgical planning
    • Monitoring recovery
    • Guiding rehabilitation
  • Computed tomography (CT) is used widely due to accessibility, efficiency and lower cost than Magnetic resonance imaging (MRI)

Mechanisms of injury

  • Non-missile injury
    • A form of closed head injury
    • More common cause of neurotrauma than m...
