This abstract describes the steps that have been taken to enable high resolution T2-weighted imaging of the inner ear anatomy at 7 Tesla for potential use in screening for cochlear implantation. The small size of these substructures requires high resolution imaging to detect subtle changes. The intrinsic B1+ inhomogeneities in this area were mitigated by placing dielectric pads next to the ear by placing dielectric pads next to the ear. The high spatial resolution led to improved visualization of the substructures of the inner ear anatomy.
