Brown fat uptake: 18F-FDG PET/CT scan of a 45-year-old female with luminal A invasive ductal carcinoma of the right breast: a maximum intensity projection, b transaxial PET show intense 18F-FDG uptake in the cervical, supraclavicular, paravertebral, and mediastinal regions. c The corresponding CT and d transaxial PET/CT fusion images reveal that 18F-FDG uptake is corresponding to fatty tissue, and there is no abnormal lymph node or muscle uptake, denoting activated BAT. The last row show intense FDG-avid primary lesion at the lower outer quadrant of the right breast with a metallic clip in situ, as well as foci of activated BAT at paravertebral, and mediastinal regions
