White Matter Tractography Reconstruction Ability Increases as a Function of Distance from Artifact Border. The artifact masks derived from the diffusion-weighted image volume were dilated in 2 mm increments, and the volume of white matter tracts that intersected any component of the dilated mask was computed. Components of the uncinate fasciculus (loop from temporal to ventral frontal) and inferior fronto-occipital fasciculus (occipital to temporal) in both patients' left hemisphere can be resolved within 2 mm of the artifact border by visual inspection of the orange tractography pathways. Both views are sagittal left hemisphere where A, P, S, and I indicate anterior, posterior, superior and inferior directions.
