In a child with a minor closed head injury and brief loss of consciousness, which imaging modality is most appropriate for initial assessment?

• A. MRI scan
• B. Skull radiographs
• C. CT scan
• D. Observation without imaging

Answer: (C)

In a child with a minor head injury who briefly lost consciousness, the priority is quickly ruling out potentially serious intracranial injury. Computed tomography is the best initial imaging because it can be performed rapidly and is highly sensitive for detecting acute intracranial hemorrhage, contusion, edema, and skull fractures. This swift information guides urgent decisions about treatment or safe discharge. MRI, while very good for certain injuries, takes longer, often requires sedation in children, and isn’t practical for an emergent evaluation. Skull radiographs have limited utility because they miss many brain injuries and subtle fractures. Observation without imaging may be appropriate in very low-risk cases, but the presence of any loss of consciousness increases the concern for intracranial injury, making CT the preferred initial choice.
