Mean parameter maps. Registered parameter maps from C4 across all animals demonstrated a reduction of cerebrospinal fluid (CSF) partial volume effects in the free water elimination (FWE) maps compared with diffusion tensor imaging (DTI). The radial diffusivity (RD) map, in particular, showed an improvement in the delineation between the CSF and white matter boundary. The coefficient of variation is more uniform across all animals in the FWE compared with DTI. Color image is available online.
