New MRI Technique Developed at UT Southwestern Detects Subtle but Serious Brain Injury

(HealthNewsDigest.com) - DALLAS – May 12, 2008 – A new technique for analyzing magnetic resonance imaging data, developed by researchers at UT Southwestern Medical Center, can reveal serious brain injury missed by current tests and help predict a patient’s degree of recovery.

In brain injuries sustained when the head suddenly stops moving – during a motor vehicle accident, for instance – the force can shear and damage nerve cells. This kind of injury does not show up on computerized tomography scans, the researchers said, and magnetic resonance imaging does not yet reliably detect this type of injury.

“This is a new way of measuring a common injury that has been overlooked,” said Dr. Ramón Díaz-Arrastia, professor of neurology and senior author of the paper, which appears in the May issue of the journal Archives of Neurology.
