Can an fMRI show concussion?
More broadly, our fMRI results are noteworthy for identifying a “neural signature” associated with concussion up to six years after injury, even in the absence of demonstrable cognitive deficits.
What does a brain MRI show after a concussion?
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.
What does a functional MRI of the brain show?
It may be used to examine the brain’s functional anatomy, (determine which parts of the brain are handling critical functions), evaluate the effects of stroke or other disease, or to guide brain treatment. fMRI may detect abnormalities within the brain that cannot be found with other imaging techniques.
Can fMRI detect brain damage?
It should show any physical brain damage you’ve sustained. A functional MRI is used to observe blood flow. Since increased cerebral blood flow is tied to increased brain activity, fMRI can show how the brain calls for resources during a given task.
What scan shows concussions?
It can detect bleeding or swelling in the brain as well as skull fractures. It uses a combination of x-rays and a computer to generate images of the brain structures. CT scans do expose patients to radiation. A CT scan may be indicated when it is likely a concussion requires immediate surgical intervention (surgery).
What can a neurologist do for post-concussion syndrome?
A neurologist can prescribe medication to manage neurological conditions such as pain, nerve issues, and neuromuscular disorders, including migraines and persistent headaches. Medication is a mixed bag: For some conditions, like post-traumatic migraines, it can significantly increase quality-of-life.
What is the difference between an MRI and a functional MRI?
While an MRI scan allows doctors to examine a patient’s organs, tissue, or bones, “an fMRI looks at the function of the brain,” Dr. Zucconi explains.
How long does a functional MRI take?
A typical fMRI lasts between 45 and 55 minutes.
Can MRI detect old TBI?
MRI might show brain atrophy long after the injury, which results when injured or dead brain tissue is reabsorbed after TBI. Since injured brain tissue might not fully recover after TBI, doctors might detect TBI-related changes many years following an injury.
