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 support cradle.
