DTI (Diffusion Tensor Imaging)

Serving Nationwide – Brain DTI available in all 50 States!

Texas Brain Institute is the gold standard in diagnosing and treating Traumatic Brain Injury (TBI).

Proving the details of a traumatic brain injury (TBI) has been elusive in the past. Most evidence of TBI is invisible in a routine MRI, that is because routine MRI cannot detect white matter injury that causes water to leak from neural tracts. However, state-of-the-art advanced brain MRI known as DTI (Diffusion Tensor Imaging) can accurately detect and document all the subtle injuries that interfere with the normal functioning of the operating circuits of the brain. DTI can detect this (leaking water), making it the best marker for brain injury.

At Texas Brain Institute, we use DTI data and FDA approved software to provide 3D color tractogram that illustrate where the brain has suffered white matter injury that causes water to leak from neural tracts, which has been associated with impairment.

DTI is in more than 20,000 peer-reviewed publications and courts throughout the United States are admitting DTI into evidence and allowing expert testimony based on it. DTI has been ruled admissible under Daubert and similar standards in numerous State and Federal Courts.

DTI is admissible for head injury from motor vehicle accidents, explosions, fights, anoxic injury (low oxygen) events, falls, and a wide variety of other types of events that can cause impairment of brain function.

A serious problem with DTI is the potential for misinterpretation by a neuroradiologist. Many neuroradiologists can only comment on anatomic findings. They do not see patients and can only warrant a clinical correlation. A neurosurgeon practices clinically and has a higher level of skills and training for the interpretation for brain images. A neurosurgeon can comment on clinical correlation between the patient’s symptoms and the findings on a DTI scan. Therefore, Texas Brain Institute relies on a neurosurgeon expert, an inventor of DTI (U.S. Patent – 5,560,360), Dr. Aaron G. Filler, MD Ph.D.

Dr. Filler’s proprietary DTI protocol examines and measures over 35 separate brain locations and provide specific data showing the statistical significance of each abnormal finding and correlates with patient’s report of symptoms that commenced at the time of the injury. For instance, an injury in the fornix can impair new memory formation, an injury in the hippocampal cingulum impairs attention, an injury in the middle cerebellar peduncle can cause vertigo and balance problems, injury of the basal forebrain can cause insomnia, injury to the “thinking” part of the brain in the frontal lobe, injury to long inter-connecting paths in the brain critical to speech formation, and normal conversation. None of these are even tested for in many neuroradiology reports of DTI.

Further, our Medical Director, Dr. Filler is additionally knowledgeable in the biomechanics of brain injuries, determining what part(s) of the brain are injured by certain type of impacts and can clinically evaluate a patient’s correlated neurologic status that can help determine factual causation.

Dr. Filler has been deposed hundreds of times (over 500 depositions), has testified in scores of trials throughout the US (over 80 trial testimony), and has never been excluded as an expert. Not only being a Neurosurgeon, he is also a licensed attorney who has taught both CME for physicians and CLE for attorneys in relation to DTI.
