The purpose of this study is to assess the relationship between regional white matter diffusion imaging metrics and finite element strain measures in non-concussed youth football players. Pre and postseason diffusion-weighted imaging was performed in 102 youth football subject-seasons, in which no concussions were diagnosed. The diffusion data was normalized to the IXI template. Percent change in fractional anisotropy FA (%ΔFA) images were generated. Using data from the head impact telemetry system, the cumulative maximum principal strain 1 times strain rate (CMPS1xSR), a measure of the cumulative tensile brain strain and strain rate for one season, was generated for each subject...
