“About 320,000 American troops have sustained traumatic brain injuries in Iraq and Afghanistan.” This number is shockingly high, and as doctors, we want to do everything we can to help them. That’s why a new study by Dr. David L. Brody and others at Washington University (while collaborating with Landstuhl Regional Medical Center in Germany) worked to find how blasts affected the human brain.
The study called for a highly sensitive type of MRI, a diffusion tensor imaging. Most MRI machines have the capability, and while it doesn’t take longer/cost more, the techniques have yet to be perfected. The way it works is by measuring “the movement of water in nerve fibers in the brain, [as] abnormal flow may indicate injury.”
The study performed this new exam on 63 men who had recently suffered mild traumatic brain injuries, all of whom, with the exception of one, had normal MRI results. Eighteen of these men had nerve injury, while the researchers were only expecting two. Therefore, we now know that a negative MRI scan does not rule out brain injury.
