A new tool is allowing doctors to look inside a patient's brain like never before.
A quick test checks the success of brain surgery that removed a dangerous cyst on Beverly Kaspar's brain.
She knew something was wrong when her vision started to blur.
In the past, surgery might have been considered too risky because doctors would be worried about damaging other parts of the brain.
Now, a non invasive technology called MEG is changing things.
Like other diagnostic tests that measure electrical currents, MEG measures magnetic signals from our brain in real time.
A computer then uses that info to create a 3-d image of the brain.
It pinpoints areas that control speech and movement, so doctors can avoid them while operating on almost any brain abnormality.
Richard Bucholz, M.D. St. Louis University Medical School said, “It may empower us to perform surgery and remove tumors in many more patients that we would've thought otherwise based simply on ct and MRI's.”
MEG may also help those with epilepsy by locating the source of seizures in the brain.
It can pinpoint almost any brain problem and may also be able to find damage in trauma cases even when the brain appears healthy.
