Does a normal CT or MRI scan rule out concussion after a head injury?

Doctor’s answer

No. Concussion is diagnosed mainly from the injury history, symptoms, and neurological assessment, and routine CT or MRI scans may be normal. Imaging is primarily used to look for serious structural injuries such as bleeding inside the skull or a fracture.
