Validation of Edema-invariant Multi-shell High Angular Resolution Diffusion Imaging (msHARDI)-Based Tractography With Intra-operative Cortical Stimulation

Currently, standard-of-care tractography is based on information obtained from diffusion tensor imaging (DTI). DTI is a diffusion magnetic resonance imaging (dMRI) technique that is routinely obtained on neurosurgical patients to assist in pre-operative planning. The primary objective of the proposed study is to determine the ability of msHARDI-based tractography to discern fibers in edematous brain regions.
