Tissue Optimisation Strategies for High Quality Ex Vivo Diffusion Imaging Item

SI data: T1, T2, FA and MD measurements from ex vivo rat brain tissue, prepared with various concentrations of formaldehyde, gadolinium, and at different time-points during rehydration in PBS.

MRI data in Nifti format: Diffusion-weighted datasets and DTI maps of the rat brain for high resolution (78 micron, b 4000, 30 directions) and mid resolution (150 micron, b 2000, 30 directions) acquisitions. Including:

- Preprocessed diffusion-weighted data

- Bval and bvec files

- Bruker method file with full acquisition details

- Brain mask

- DTI maps (FA, MD, AD, RD)

- Eigenvectors (V1, V2, V3)

- Diffusion tensor (DT)

- Eigenvalues (Eig)

- Red-green-blue colour maps compatible with FSL viewers and trackvis (RGB_FSL, RGB_TRK)

- Mean DWI

- b0

- Anisotropic power (AP6np)
