Brain Imaging with MEG
Did you know that by spotting specific brain biomarkers, researchers wre able to diagnose PTSD sufferers with 90% accuracy? Using a brain imaging method called magnetoencephalography (MEG), they scanned the brains of 74 U.S. veterans with PTSD, and 250 civilians without PTSD. Whereas CT scans and MRIs record brain signals every few seconds, MEGs can do it by the millisecond, catching biomarkers and brain activity that the other tests inevitably miss.
