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. WebThe presence of brown fat on FDG PET has the potential to lead to misinterpretation and unneeded invasive tests, which can be avoided by using measures such as ensuring the patient is warm, reducing FDG uptake in brown fat before the procedure, and correlating PET uptake to a specific anatomic location with PET/CT fusion imaging.
Brown adipose tissue (BAT) (also known as brown fat) is one of two types of adipose tissue (the other one being white fat) important for producing thermal energy (heat, non-shivering thermogenesis), especially in the newborn.
