Information about this survey

  • ​We are trying to find out about opinions and behaviours within the radiographer and MR technologist community surrounding the MR scanning of patients with cochlear implants (CIs). For clarification, we would like to check that we’re all talking about the same devices and that there is no confusion.
  • This is a picture of a cochlear implant:

 

 

 

 

 

 

 

 

 

  • A cochlear implant has an outside component that is typically worn behind the ear, but can be worn on the clothing in young children. This connects to a coil that you will see attached to the scalp behind the ear. In the centre of the coil is a magnet, which keeps the outside component in place. The internal component of a cochlear implant contains, among other things, a matching coil and magnet under the scalp.
  • With some models of cochlear implant, the internal components are MR unsafe. Others are MR conditional at some field strengths, often with limits on the allowed SAR, RF or gradients, and/or following surgical removal of the internal magnet.
  • Our questions do not relate to bone-anchored hearing aids, conventional hearing aids, or any other hearing device or implanted device.
  • All responses you give will be completely anonymised and we will not store any identifiable information.
  • We will collate responses together and publish statistical analyses performed on these numbers. We may publish parts of written responses, but this will be entirely anonymised.
  • We are not trying to make value judgements about current practice or target any person or group, only to capture opinions and practices/behaviours.
  • YOU WILL NOT BE REQUIRED TO PROVIDE ANY IDENTIFYING INFORMATION IN THIS QUESTIONNAIRE, NOR WILL ANY ATTEMPT BE MADE TO IDENTIFY YOU FROM THE ANSWERS YOU GIVE.
