Can a CT scan detect a mild concussion?

Generally, CT scans cannot detect mild concussions. If necessary, it is recommended to consult a doctor's opinion. Detailed analysis is as follows:

The pathophysiological changes caused by mild concussion are usually temporary and do not lead to significant structural damage to brain tissue or blood vessel rupture. CT scan is a commonly used imaging method that can clearly show the anatomical structures within the skull. However, it is difficult for CT scans to capture abnormal anatomical structures associated with transient brain functional impairments that do not cause obvious structural changes.

In addition, CT may not be sensitive enough to detect minor anatomical structural changes or functional alterations. Biochemical and functional changes possibly induced by mild concussion may be limited to microscopic levels such as neuronal activity patterns or neurotransmitter release. These microscopic changes are difficult to detect on CT scans, as CT primarily uses X-ray imaging and focuses more on displaying structural changes in brain tissue, such as bleeding, swelling, or fractures.

In daily life, maintaining adequate sleep and rest, avoiding excessive emotional excitement or external stimuli, can help in the recovery of brain function.
