Abstract

•Diffusion tensor imaging (DTI) was used to study white matter tracts in the brain.•Fractional anisotropy (FA) and probabilistic tractography quantified the DTI metric.•Nine voxel clusters differed between the two groups with all 9 showing increased FA for the tinnitus (+) group.•These predominantly left sided voxel clusters may play a role in noise-induced tinnitus.
