Coronal maps of T2 difference from baseline of abdominal fat layer (volunteer 2) after cooling (a) and heating (b). c Temperature, recorded by the probes and the corresponding change in T2 for volunteer 1 during cooling and heating. d Relationship between temperature and T2 at the locations of the probes. The temperature change in the middle of the fat layer, where T2 maps were acquired, was likely smaller than on the surface due thermal isolating properties of the fat layer
