ABSTRACT
Objective Magnetic resonance diffusion tensor imaging (DTI) was applied to study the cantral auditong pathway in patients with .Methods A total of 30 cases of acquired hearing loss patients were divided into 2 groups ,group 1 (15 ,sudden deafness) and group 2 (15 ,with duration up to 2 years SNHL group from the time of onset) .A total of 15 cases of normal-hearing patients on MRI examination were selected as the control group for the same period .All subjects received DTI of whole brain .The values of the whole brain DTI were obtained from the inferior colliculus and lateral lemniscus ,consisting of the fractional anisotropy (FA) ,radial diffusion (RD) ,axi‐al dispersion (AD) and mean diffusivity .Results There were significant differences(P0 .05) .Conclusion There was no obviously abnormal change on the central auditory processing in sudden deafness group ,but significant destruction was found on 2 years SNHL group .It indicated that central auditory processing of the history of sensorineural deafness affected the structural changes of the central au‐ditory pathway .
