The route of the cochlear nerve can be imaged using computed tomography (CT) or magnetic resonance imaging (MRI). To gain information about the cochlear nerve, we conducted a trial measuring the width of the cochlear nerve canal (CNC) using CT. When we examined images of the route of the cochlear nerve on MRI, both in ears with congenital sensorineural hearing loss (SNHL) and normal ones, we found that in ears in which the CNC was narrower than 1.5 mm with CT, images of cochlear nerve deficiency could be seen in that ear with MRI.
