Neuropsychologist researcher and professor Erin Bigler, PhD. recently spoke about the advances in images of post-concussion brains. 
As discussed here, concussions or mild traumatic brain injuries may not show up on standard MRI or CT images. Dr. Bigler described a new technique for analyzing MRI scans called "diffusion tensor imaging" or DTI. This technique illustrates the direction of
Proving Mild Traumatic Brain Injury
Most victims of a Mild Traumatic Brain Injury recover fully within one year of their injury. But, sometimes, victims can be left with long-term cognitive problems that affect both their jobs and 
their family lives for years to come. Despite the potentially devastating effects of a mild brain trauma — also known as a " concussion
MRI’s, PET Scans, and Traumatic Brain Injury
Some traumatic brain injuries can be seen on an MRI scan. Many, however, cannot. The structural 
damage caused by the trauma is just too subtle. Of course, even subtle changes in brain structure can cause profound changes in brain functioning. Simply because the brain injury cannot be seen on an MRI, it doesn’t mean that it
Recognizing “Mild” Traumatic Brain Injury (Concussion)
Doctors once believed that, whenever a blow to the head resulted in a brain injury, the victim would lose consciousness. Without a loss of consciousness, they would say, there could be no brain injury. That’s no longer the case. Now, medical professionals agree that a brain injury can result without the victim ever blacking out
