Diagnostic imaging in concussion is not generally recommended, and this is supported by multiple national and international concussion guidelines. There are, however, complicating factors that may be present where imaging may be helpful. The most commonly available imaging modalities available are X-ray, computed tomography (CT), and magnetic resonance imaging (MRI). While X-ray and MRI are not indicated in the acute setting, there may be certain clinical scenarios where a head CT may be indicated, and there are multiple head CT decision support tools available for use to help facilitate this decision-making. Additionally, there are many other imaging modalities being investigated to determine what role each may play in the diagnostic evaluation of concussion, although more research is needed before these are recommended clinically.
