Concussion comes from the Latin word concutere meaning “to shake violently.” In essence an mTBI, or concussion, is when the brain experiences an injury significant enough to cause some of the following problems:
The skull usually does a good job of protecting your brain. When you experience an mTBI (mild traumatic brain injury) the FA in the brain’s white matter may show low FA. Low FA is an abnormality and indicates an injury to the nerve cells. High FA has been observed in acute and subacute injuries.
Tractography creates beautiful images of the brain’s white matter pathways. This technology is of critical importance to neurosurgeons when they evaluate for tumors or other brain surgery. However tractography is of no value when we look for objective evidence of the microscopic nerve damage resulting from a concussion. A concussion diagnosis requires the use of quantitative DTI.
If you have concerns regarding a concussion injury or wish to schedule an appointment for a quantitative DTI with the Concussion Group, just call (504) 883-3544 or fill out the request appointment form.
