High diffusion and spatial resolution Diffusion Tensor Imaging (DTI) of the brain

High diffusion and spatial resolution Diffusion Tensor Imaging (DTI) of the brain (1.5mm isotropic voxel size, 64 diffusion directions). Colour-coded orientation map fused on an anatomical 3D T1-w MR image (A, B, C) and whole brain fiber-tracking map (D). Slice acceleration (SMS, Multi-Band) can be used to decrease the scan time and/or achieve higher spatial/diffusion resolution. High diffusion resolution is necessary for advanced diffusion models (e.g. Kurtosis) and for advanced post-processing procedures (e.g. constrained spherical deconvolution, which addresses the crossing fibers issue). Image dataset acquired at 3 Tesla. Courtesy of Bac Nguyen.
