Despite the presence of behavioral deficits, mild chronic traumatic brain injury (TBI) often occurs without any anatomical MRI but quantitative Diffusion Tensor Imaging (DTI) have revealed subtle differences at lower field-strengths suggesting that ultra-high field MR might have additional abilities. Ten TBI patients and ten age matched controls were scanned at 7T. Patients showed statistically significantly lower mean FA, higher ADC and shorter fibers, indicating the improved diagnostic potential of 7T.
