Auditory neural pathway evaluation on sensorineural hearing loss using diffusion tensor imaging

Diffusion tensor imaging is a nevvinvivo tool not only for the assessment of white matter structural integrity but also for diagnosis and assessment of disease conditions which disturb tissue structural coherence. In this study, we investigated the integrity of auditory pathway in patients of sensorineural hearing loss by means of fractional anisotropy of water diffusion to see any subtle changes of auditory pathways resulting from sensorineural hearing loss. In addition, this study suggests that the diffusion anisotropy measured by diffusion tensor imaging is highly sensitive to otherwise subtle disease processes not normally seen with conventional magnetic resonance imaging or computed tomography contrast.
