Brown adipose tissue (BAT) is a special adipose tissue which burns fat and dissipates energy in heat. As a result, heat production capacity of BAT is considered to represent its activity directly. In this study, we aimed to evaluate the accuracy of the proposed magnetic resonance fat-referenced PRFS method on BAT in vivo in rat after activated by Norepinephrine. The preliminary results show the PRFS based thermometry can describe the temperature change in activated BAT accurately, implying that magnetic resonance thermometry (MRT) is a useful tool to characterize the BAT activity.
