There
are two types of fat tissues, white adipose tissue (WAT) and brown adipose
tissue (BAT), which essentially perform opposite functions in whole body energy
metabolism. Cold exposure activates adrenergic receptor in the brown adipose tissues,
and improve the separation of WAT and BAT. In this study we have evaluated the
longitudinal changes of fat fraction (FF), and relaxation times (T2
and T2*) of interscapular brown adipose tissue (BAT) of rats under
thermoneutral and short term cold exposure, and validated with histology and
UCP1. PET-CT was performed to visualize the activated BAT.
