Traumatic Brain Injury (TBI)
Concussions and Traumatic Brain Injuries can be extremely debilitating, even when a routine brain MRI comes back normal. Diffusion Tensor Imaging (DTI) is a powerful brain imaging sequence that visualizes the fiber tracts in the brain that can’t be seen on a traditional MRI. Some physicians or specialists in post-processing utilize software that performs tractography or calculates functional anistropy. This data may help physicians evaluate the health of the fibers to gain information as to the severity of a concussion or provide baseline information if a future injury occurs.
It can also provide precise number values that can help determine the severity of injury. In sports, this number can help athletes understand more about concussion and provide baseline information if a future injury every occurs. Diffusion tensor imaging can provide an index of white matter integrity in traumatic brain injury as well as a potential biomarker reflective of outcome.
Treatments for Head Injuries
Given the nature of the injury and the population examined, up to 90% of patients who experience a concussion can develop postconcussive syndrome (PCS). This syndrome can consist of a persistence of any combination of the following symptoms after a head injury: headache, nausea, emesis, memory loss, dizziness, blurred vision, emotional lability, or sleep disturbances.
Treatments for head injuries will vary depending on the severity of the injury or concussion, including factors such as the type of injury, loss of conscientiousness and the treating physician. Injuries that are un-diagnosed may cause long-term disability and impairment. The utilization of DTI can may provide insightful data to the treating physician to aide in the treatment recommendations.
