Flow chart of steps used to analyze DTI asymmetries. The non-diffusion-weighted images (also called b0 images) from all subjects were used to make a group “average-shape” brain, or mean deformation template (MDT), and they were nonlinearly registered to this template. The deformation fields were also applied to maps of mean diffusivity (MD) and anisotropy (FA, GA) to align them all to the common template. Statistical maps were made to show the mean level of asymmetry in different brain regions. Genetic analysis of the variance in fiber characteristics was performed at each location in the brain.
