DTI Shows Long Term Impact of mTBI in Blast Exposure

At the December 2, 2013 annual meeting of the Radiological Society of North America (RSNA), researchers from St. Louis University School of Medicine in St. Louis, MO, presented evidence utilizing diffusion tensor imaging (DTI) to show that “soldiers who suffered mild traumatic brain injury induced by blast exposure exhibit long‑term brain differences.”

According to the article uploaded by PR Newswire, researchers compared DTI derived fractional anisotropy (FA) values in ten veterans who had been diagnosed with mild TBI with those of ten healthy controls.  “Comparison of FA values showed significant differences between the two groups, and there were significant correlations between FA values and attention, delayed memory, and psycho motor tests scores.  Since the victims were, on average, more than four years removed from their injuries, the results suggest the presence of a long‑term impact of blast injury on the brain.”
