Can't Lie To An MRI

"A scientist at the Medical University of South Carolina has found that magnetic resonance imaging machines also can serve as lie detectors.

The study found MRI machines, which are used to take images of the brain, are more than 90 percent accurate at detecting deception, said Dr. Mark George, a distinguished professor of psychiatry, radiology and neurosciences.

That compares with polygraphs that range from 80 percent to 'no better than chance' at finding the truth, George said.

His results are to be published this week in the journal Biological Psychiatry. "
