What Is DTI MRI?
A Diffusion Tensor Imaging (DTI) is a protocol cleared by the Food and Drug
Administration (FDA) to show where and how a person has been affected by a critical
traumatic injury. The DTI MRI has a wealth of peer-reviewed evidence in more than 20,000
publications. The veracity of the evidence is strong enough that courts also accept it
as evidence in personal injury cases involving head injuries.
The DTI MRI is more sensitive than regular MRIs, so that it will give you more details
about your head injury, whether you’ve experienced an explosion, anoxic injury, motor
vehicle accidents, fight, fall, or another violent event. The DTI validates the injury.
So, if brain trauma does exist, a DTI is your best option to detect an injury.
Why Would You Need a DTI?
Your doctor or lawyer might order or request a DTI MRI if you have experienced a
possible traumatic brain injury, disorder, or abnormality. A legal or medical expert
needs evidence and documentation on how the injury may affect your health. The DTI is
just another way of looking at the MRI scan data. It’s more accurate than the PET Scan,
CAT Scan, or SPECT for determining the presence and severity of your traumatic brain
injury. Particularly in cases where a CT or even a traditional MRI doesn’t show
abnormalities, the DTI can show the real impact of your high-velocity accident. The DTI
can also show cognitive decline as part of neuropsychological testing.
If a DTI MRI does show a bran abnormality, an experienced radiologist will determine it
means. It could be that the abnormality is an old traumatic brain injury, an old stroke,
an infection from some time ago, or even a brain surgery that you had.
Another reason for the abnormality could be a congenital defect, although that type of
abnormality would typically appear as a global issue. The abnormality will probably
appear as a directional issue if you have been affected by a traumatic brain injury or
event. If you hit the left side of your head in a car accident or other blow to the
head, for example, your radiologist will probably notice a decrease in white matter
tracts on the left side of your brain where you hit your head.
