Which imaging technique is best for diagnosing a concussion?

A Functional Magnetic Resonance Image (fMRI) is an imaging technique used to diagnose concussion and recognizes changes in the brain while you are asked to engage in cognitive tasks. Most people have heard of an MRI and but fewer have heard of a functional MRI (fMRI).

Can you see a concussion on imaging?

Brain scans are usually not helpful for a concussion. An MRI creates clear images of brain tissue. But these scans cannot show if you have a concussion. A concussion is different from a fracture or bleeding. A concussion affects how your brain works, and most people recover within a few weeks.

When is MRI indicated concussion?

An MRI may be more appropriate if imaging is needed 48 hours or longer after an injury to evaluate persistent or worsening symptoms or where there is a concern for underlying pre-existing conditions (eg. headache or seizure disorder, arteriovenous malformation, Chiari malformation, etc.)

What is the role of diagnostic imaging in concussion diagnosis?

Magnetic resonance imaging is more commonly used as a secondary test for the investigation of persistent symptoms. New imaging techniques are currently being developed to detect the molecular and cellular changes underlying concussion that are invisible with standard structural imaging.

Do you need a CT scan for a concussion?

It is important for the health care provider to examine you for a possible concussion or another injury. The health care provider may order a CT (computerized tomography) scan of the brain to make sure you do not have a fractured skull or a serious brain injury. But most of the time these scans are not needed.

What tool is used to diagnose concussions?

Cognitive tests — such as ImPACT® (Immediate Post-Concussion Assessment and Cognitive Testing) — are key tools we use to diagnose signs of a concussion. The ImPACT test looks at your: Verbal and visual memory. Brain processing speed.

How can u tell if someone has a concussion?

1. Headache or “pressure” in head.
2. Nausea or vomiting.
3. Balance problems or dizziness, or double or blurry vision.
4. Bothered by light or noise.
5. Feeling sluggish, hazy, foggy, or groggy.
6. Confusion, or concentration or memory problems.
7. Just not “feeling right,” or “feeling down”.

Which is better CT scan or MRI for brain?

Spine – MRI is best at imaging the spinal cord and nerves. Brain – CT is used when speed is important, as in trauma and stroke. MRI is best when the images need to be very detailed, looking for cancer, causes of dementia or neurological diseases, or looking at places where bone might interfere.

Should I go to ER after hitting my head?

Emerman says patients who’ve suffered a head injury should visit the Emergency Department immediately if they: Lost consciousness or became confused/disoriented after they were injured. Suffered the injury at a high speed (car or bike accident, a steep fall, etc.) Are vomiting or feel nauseated.
