Mean diffusivity maps in noise-induced hearing loss

Mean 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 mean diffusivity values in the left inferior longitudinal fasciculus and left inferior fronto-occipital fasciculus. 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.
