What does a brain MRI looking for and what can it rule out such as MS Alzheimers etc...?

A Celiac ask...?


Answers:    MRI's use high-powered magnets to see internal body structures and their function. They're better than a CT scan (computerized tomography). Brain MRI's can see blood flow, areas of high activity (areas where on earth the brain is working hard), atrophy (shrinking), areas affected by stroke...the list go on and on. It's highly detailed. http://www.radiologyinfo.org/en/info.cfm...

To rule out MS: this requires blood work, MRI's, lumbar puncture, and a slew of other tests; an MRI alone won't do it. Many associates with MS will have lesion (kinda like scaring) on their brain and spinal cord that show up on an MRI, but an MRI isn't the only testing used to diagnose a patient with MS. If they're conducting tests someone for MS and lesions aren't found on an MRI, other tests are still perform to rule out MS.

The only way to truly diagnose alzheimers is during autopsy. Alzheimers is presumed contained by persons who are exhibiting signs and symptoms of the condition, but it cannot be "officially" diagnosed until brain tissue is examined under a microscope.

Magnetic resonance imaging (MRI) is a assessment that uses a magnetic field and pulses of radio current energy to take pictures of the skipper. In many cases MRI gives information that cannot be see on an X-ray, ultrasound, or computed tomography (CT) scan.

For an MRI test, you lie beside your head inside a special machine (scanner) that have a strong magnet. The MRI can show tissue damage or disease, such as infection, inflammation, or a tumor. Information from an MRI can be saved and stored on a computer for more study. Photographs or films of particular views can also be made. See MRI images of a party who has had a stroke or a requisition.

In some cases, a dye (contrast material) may be used during the MRI to show pictures of structures more clearly. The dye may help show blood flow, look for some types of tumors, and show areas of inflammation.
