Abstract

Several interesting physiological variants have been identified with PET/CT imaging. Foremost among these is the identification of brown fat as FDG-avid tissue. Brown fat is heat-producing tissue that occurs more frequently in young patients and the degree of glucose metabolic activity appears to be related to temperature. FDG uptake in brown fat occurs most frequently in the supra-clavicular region but can also be seen as perivascular fat in the mediastinum. Prior to PET/CT increased uptake was always attributed to FDG uptake in striated muscle. More detailed information is provided in chapter 7.
