Is it true that a concussion is usually diagnosed by neuroimaging tests such as CT scan or MRI?

• A. True
• B. Not sure
• C. False
• D. Depends on severity

Answer: (C)

Diagnosing concussion is done mainly through clinical evaluation rather than imaging. The typical approach relies on the history of head injury, the presence of symptoms (such as headache, dizziness, confusion, amnesia, balance problems), and a focused neurologic/exam assessment. Neuroimaging like CT or MRI is not usually needed to confirm a concussion because many concussions don’t produce visible structural changes, and imaging results are often normal even when concussion symptoms are present. Imaging becomes important when there are red flags or signs suggesting a more serious injury—such as suspected skull fracture, worsening or new neurological deficits, repeated vomiting, severe or rapidly progressing headache, or altered consciousness. In the acute setting, CT is commonly used to quickly rule out life-threatening injuries, but it does not confirm concussion. MRI might detect subtle issues in some cases, but it isn’t practical as a first-line tool for typical concussion and is more often reserved for persistent or unclear cases.
