In post mortem MRI, the absence of body temperature autoregulation can lead to significant local heating in the sample from RF absorption and heat from the environment. This can interfere with scanning (such as diffusion measurements) and in unfixed samples, accelerate tissue decomposition. In this work, a temperature control system is presented which enables prolonged scanning of post mortem samples at a stable temperature while preserving tissue.
