      Brain atrophy outcomes of 590 patients were analyzed by the percentage brain volume change measured by structural image evaluation with normalization of atrophy on 2D-T1WI and 3D-T1WI and the percentage lateral ventricle volume change, measured by VIENA on 2D-T1WI and 3D-T1WI and NeuroSTREAM on T2-FLAIR examinations. The median annualized percentage brain volume change was -0.31% on 2D-T1WI and -0.38% on 3D-T1WI. The median annualized percentage lateral ventricle volume change was 0.95% on 2D-T1WI, 1.47% on 3D-T1WI, and 0.90% on T2-FLAIR. The authors conclude that brain atrophy was more readily assessed by estimating the percentage lateral ventricle volume change on T2-FLAIR compared with the percentage brain volume change or percentage lateral ventricle volume change using 2D- or 3D-T1WI.

      White Matter Changes Related to Subconcussive Impact Frequency during a Single Season of High School Football
      S.J. Kuzminski, M.D. Clark, M.A. Fraser, C.C. Haswell, R.A. Morey, C. Liu, K.R. Choudhury, K.M. Guskiewicz and J.R. Petrella

      Seventeen male athletes (mean age, 16 years) underwent MR imaging before and after the football season. Changes in fractional anisotropy across the white matter skeleton were assessed with Tract-Based Spatial Statistics and ROI analysis. The mean number of impacts over a 10-g threshold sustained was 414. Voxelwise analysis failed to show significant changes in fractional anisotropy across the season or a correlation with impact frequency, after correcting for multiple comparisons. ROI analysis showed significant decreases in fractional anisotropy in the fornix-stria terminalis and cingulum hippocampus, which were related to impact frequency. The authors conclude that subclinical neurotrauma related to participation in American football may result in white matter injury and that alterations in white matter tracts within the limbic system may be detectable after only 1 season of play at the high school level.
