Abstract：Objective To investigate the clinical value of MR hydrography of inner ear in evaluation of children with co-chlear implantation .Methods 24 children with hearing impairment scheduled for cochlear implantation were scanned by use of Siemens Avanto 1 .5 T MRI scanner .The water signal in the region of inner ear was collected and sent to the work-station for image post-processing .Finally ,the imaging manifestations and characteristics were analyzed .Results Of these 24 cases ,18 had normal inner ear morphology ,1 case had cochlear malformation associated with enlarged vestibular aque-duct ,3 cases only had the dilated vestibular aqueduct ,1 case had abnormal semicircular canal ,and ,1 case had Mondini malformation .Conclusion MR hydrography can clearly show the fine anatomical structures of membranous labyrinth and internal auditory canal in the inner ear ,thereby providing important information for the diagnosis of inner ear lesions as well as for the preoperative evaluation for cochlear implantation .
