Axial diffusivity maps in noise-induced hearing loss
Axial diffusivity maps show significant differences between patients with mild noise‐induced hearing loss, relatively severe noise‐induced hearing loss, and healthy controls. The red-yellow highlighted areas indicate higher axial diffusivity values in the left inferior longitudinal fasciculus, left inferior fronto-occipital fasciculus, right corticospinal tract, right external capsule, and right superior longitudinal fasciculus; they are significantly lower in the left corticospinal tract, right anterior thalamic radiation, and right superior cerebellar peduncle. The background image consists of the standard MNI T1-weighted template at 1 mm thickness and the fractional anisotropy skeleton (green). (The red-yellow scale represents regions of significant difference, with red representing regions of greatest difference.) The right-hand column is the corresponding section sagittal/coronal position. (Source: Huang R, Wang A, Zhang Y, et al.
