The soldier on the fringes of an explosion. The survivor of a car wreck. The football player who took yet another skull-rattling hit. Too often, only time can tell when a traumatic brain injury will leave lasting harm - there's no good way to diagnose the damage.

Now scientists are testing a tool that lights up the breaks these injuries leave deep in the brain's wiring, much like X-rays show broken bones.

Research is just beginning in civilian and military patients to learn if this new kind of MRI-based test really could pinpoint their injuries and one day guide rehabilitation. It's an example of the hunt for better brain scans, maybe even a blood test, to finally tell when a blow to the head causes damage that today's standard testing simply can't see.

"We now have, for the first time, the ability to make visible these previously invisible wounds," says Walter Schneider of the University of Pittsburgh, who is leading development of the experimental scan. "If you cannot see or quantify the damage, it is hard to treat it."
