The SNR gain of cryogenically cooled resonators (CCR)is supposed to generate high fidelity DTI data with high in-plane resolution and thin slices in order to get close to isotropic voxel resolution. That way, accurate fractional anisotropy (FA) mapping and improved isotropic 3D DTI fiber reconstruction could be obtained. The aim of this study is to keep the overall scanning time at approximately 30 minutes in order to enable the application of the scan protocol to in-vivo cohort studies aiming at DTI comparisons of murine brain at the group level.
