Diffusion weighted images and registration. a Representative b = 0 image (i.e. no diffusion weighting). Signal-to-noise (SNR) was roughly 33 ± 1 across all animals. b Diffusion weighted image of the same slice as in (a). SNR was roughly 24 ± 1 across all animals. c Rendered diffusion tensors from a single short axis slice superimposed on the corresponding finite element mesh
