Diffusion imaging: multi-shell DTI on a whole-body 3T scanner versus a head-only MAGNUS 3T for traumatic brain injury evaluation

Diffusion imaging has progressed beyond standard DTI to mutli-shell and non-Gaussian techniques to improve upon the sensitivity of detecting multiple fiber angles in a voxel. Newer high-gradient scanners are able to further expand the capabilities of these advanced DTI sequences to help us improve upon the detection of complex fiber tracks in voxels, which is important in the evaluation and treatment of traumatic brain injury. These new technologies hold promise to improve our understanding of the movement of microcellular fluids.
