Which statement about neuroimaging in concussion management is true?

• A. Imaging not routinely required unless persistent or progressive symptoms, abnormal exam, skull fracture signs, or failure to improve.
• B. Imaging is required in all suspected concussions.
• C. Imaging should be done before any clinical evaluation.
• D. Imaging replaces clinical examination.

Answer: (A)

In concussion management, neuroimaging is used selectively rather than routinely. The best statement reflects this approach: imaging is not required for every suspected concussion, but is indicated when there are red flags or the symptoms are persistent or worsening, when the exam is abnormal, when signs of skull fracture are present, or when there is failure to improve over time. This fits clinical practice because most concussions do not involve a structural brain injury that imaging would reveal, and CT or MRI exposes patients to unnecessary radiation, costs, and delays in care if used indiscriminately. Imaging done before a thorough clinical evaluation isn’t appropriate, since decisions about whether imaging is needed depend on the history and examination findings. And imaging does not replace the clinical examination; physicians rely on serial neuro checks and symptom assessment to guide management, with imaging supporting only when signs point toward possible intracranial injury.
