A military study done at Washington University in St. Louis, Missouri and abroad looking that the brains of blast injured servicemen from Iraq and Afghanistan shows a ‘early first step’ toward possibly having the imaging technology to discover concussions;
Using a highly sensitive type of magnetic resonance imaging, researchers studied 63 servicemen wounded by explosions in Iraq or Afghanistan and found evidence of brain injuries in some that were too subtle to be detected by standard scans. All the men already had a diagnosis of mild traumatic brain injury (synonymous with concussion), based on symptoms like having lost consciousness in the blast, having no memory of it or feeling dazed immediately afterward.
As reported in the New York Times Dr. David Brody and his colleagues have posted a study in the New England Journal of Medicine looking at the diffusion tensor imaging (DTI) a function of a standard MRI. This type of imaging study does not take any longer to perform but can look even ‘deeper’ in the brain for subtle changes; Continue reading
