WebCase Discussion. Activated brown adipose tissue (BAT) is a potential pitfall on 18-FDG PET/CT. The PET/CT study has been performed on January and the patient is relatively young. It is well known that BAT accumulation is inversely proportional to age and its metabolism is extremely stimulated by cold temperature. WebAs with pediatric patients, brown fat FDG uptake is a common cause of focal uptake in adult necks, and is potentially problematic when evaluating patients with head and neck cancers as well as lymphoma. 15 The key for identifying this pitfall is localization of the uptake to fat density on CT and lack of corresponding soft-tissue mass.
