Computed Tomography and/or Magnetic Resonance Imaging Before Pediatric Cochlear Implantation? Developing an Investigative Strategy

Abstract

Dual-modality imaging with HRCT and MR of petrous bone and MR brain in the precochlear implant pediatric population detects abnormalities related to deafness, which would not otherwise be found using either modality alone. There is overlap between the imaging modalities in the type of abnormalities detected, and we present a case for selective use of HRCT within a diagnostic algorithm, using the patient risk factors we have identified.
