Going Beyond Diffusion Tensor Imaging Tractography in Eloquent Glioma Surgery-Hiqh-Resolution Fiber Tractography: Q-Ball or Constrained Spherical Deconvolution?

摘要

OBJECTIVE: As a result of the resolution of intravoxel fiber crossing, high-resolution fiber tractography (HRFT) provides advantages over conventional diffusion tensor imaging (DTI) for fiber tractography (FT). Nevertheless, neurosurgically applied FT is still predominantly based on DTI. Although the application of HRFT is evolving, there is still a lack of data about which method should be preferred. With this prospectively designed study, we present our initial experience comparing an analytical Q-ball imaging (QBI) approach with constrained spherical deconvolution (CSD) and conventional DTI-FT considering a particularly neurosurgical perspective.
