A Breakthrough in Head-Trauma Research?

In a study of ex-pro athletes, researchers have found that a specialized, noninvasive imaging technique called magnetic resonance spectroscopy (MRS) may help diagnose chronic traumatic encephalopathy (CTE), a disorder caused by repeated head trauma that currently can only be definitively diagnosed via an autopsy. Results of the study were presented in Chicago on Wednesday at the annual meeting of the Radiological Society of North America (RSNA) and are being called a preliminary first step toward diagnosis and maybe even treatment.

"The devastating effects of brain injuries suffered by pro football players who repeatedly suffered concussions and subconcussive brain trauma during their careers have put the spotlight on CTE," says lead author Alexander Lin, a principal investigator at the Center for Clinical Spectroscopy at Brigham and Women's Hospital in Boston. "However, blows to the head suffered by all athletes involved in contact sports are of increasing concern."
