Anaesthesia is usually required for the immobilisation
of animals for imaging. This induces a heat loss that
must be artificially offset. It is commonplace for warm
fluids (piped liquids or circulating air) to be used to
provide this heat but these systems require significant
space in which to circulate. We demonstrate a resistive
heating system that creates no discernible artefacts in
MR images or spectroscopy, and which requires no
additional space as it embedded within the animal
