Proton resonance frequency-shift based MR temperature imaging was introduced into the rectal temperature measurement in cooling dead bodies in order to estimate the time of death in legal medicine. A series of MR temperature difference maps in cooling dead rats could be obtained. Moreover, distribution of cooling rates among pelvic tissues was observed and shown to be related to body position.
