Does a CT scan always show a concussion?
First, bruising suggests bleeding, and a concussed brain does not bleed. In fact, images of a concussed brain may look normal as concussions generally do not show up on MRI or CT scans. This is because a concussion is an injury that disrupts the normal functioning of the brain.
Will a CT scan show brain bleed?
CT scans can show if there is swelling or bleeding in the brain or a fracture in the skull. If you have signs of a serious injury, a CT scan is usually the best first test to diagnose it.
Can a head CT scan miss something?
First, CT scans are relatively poor at identifying soft tissue injuries. As a result, CT scans on average miss 10–20% of abnormalities that an MRI would detect. Second, TBIs can take time to develop on a physical level. A microscopic brain bleed might not appear on a CT scan for hours or even days, for example.
What happens if you hit the back of your head?
That means that if you hit your head and the brain swells, there will be less room for blood, which could mean the brain will become even more injured. Or, if you hit your head and the blood vessels in your brain start to bleed, the brain tissue may end up getting squished to make room for the blood.

Can a CT scan of the head show dementia?
CT and MRI scans, which reveal the anatomic structure of the brain, are used to rule out such problems as tumor, hemorrhage, stroke, and hydrocephalus, which can masquerade as Alzheimer’s disease. These scans can also show the loss of brain mass associated with Alzheimer’s disease and other dementias.
How do you know if your brain is bleeding after hitting your head?
