Which statement best describes the relationship between imaging and concussion diagnosis as described in the material?

• A. CT or MRI always confirms concussion.
• B. Imaging is not used to diagnose concussion at all.
• C. Clinical evaluation and symptoms are essential to diagnose concussion.
• D. Imaging alone is sufficient to diagnose concussion.

Answer: (C)

Concussion is diagnosed based on what the patient reports and how they present after a head impact. The key idea is that the diagnosis comes from clinical evaluation—observed symptoms, their timing, and the history of the injury—rather than from imaging findings. CT or MRI are valuable to rule out other problems like bleeding, swelling, or skull fracture, or to assess persistent or alarming symptoms, but they do not confirm a concussion on their own. Many concussions have normal imaging results, so a normal scan does not rule out concussion. That’s why the best statement is that clinical evaluation and symptoms are essential to diagnose concussion. Im aging alone cannot establish the diagnosis, and imaging is not used as the sole basis for it.
