Multi-Spherical Diffusion MRI: An in-vivo Test- Retest Study of Time-Dependent q-space Indices

We assess the test-retest reproducibility of time-dependent q-space indices (qτ-indices) in three C57Bl6 wild-type mice. To estimate qτ-indices from the four-dimensional qτ diffusion signal - varying over 3D q-space and diffusion time - we use our recent Multi-Spherical Diffusion MRI (MS-dMRI) method. Using MS-dMRI we could reliably estimate qτ-indices for two out of three subjects, where acquisition artifacts caused the offsets of the last subject.
