It happens in a flash: you get into a car accident, and you are rendered unconscious. Luckily, you are alive after the wreck, but you suffer from a traumatic brain injury as a result of it. Traumatic brain injuries can not only happen in car accidents but other types of motor vehicle and sports-related accidents as well. The effects of this kind of brain injury can take a toll on your daily life, but luckily some tests can help to evaluate the severity of it so that you can be treated accordingly. One of the most common forms of testing, which is called Diffusion Tensor Imaging (DTI), has been groundbreaking in finding traumatic brain injuries in patients. Here are some facts about DTI, and how it can help you live a full, happy, healthy life.
How Does DTI Work?
To understand how DTI works, we also have to know the material our brain is made out of and how it operates. The brain is made of two kinds of matter: white and gray. The gray matter acts as a collector of the millions of signals your brain gives off each day, and your white matter is used to send those messages from the gray matter to the rest of your body. The white matter contains something called axons, which are the actual passageways in your body.
One of the most unique and advanced aspects of DTI is what it tracks to find the traumatic brain injury. Using the white matter’s axonal tracts, DTI actually traces the amount of water that is flowing to and from them in your brain. The DTI scan itself lights up the areas of the brain where the water is flowing correctly through the axons, allowing the areas where water is not moving to be dark. The blockage of water in those passageways is what a traumatic brain injury looks like on a DTI scan.
*Please note – DTI is only done at our Woodbridge Radiology facility, and is not offered at North Dover Radiology at this time.
