Neurofibromatosis type 2 (NF2) patients commonly have bilateral vestibular schwannomas, which typically require regular monitoring with MRI. However these patients also have cochlear implants which makes MRI challenging. We have used Slice Encoded Metal Artefact Correction (SEMAC) to improve the imaging of IAMs in patients with cochlear implants in-situ. The implementation of SEMAC imaging reduced the geometric distortion and the volume of the signal void around the implants by over half.
