The role of active brown adipose tissue in human metabolism.

Purpose: The presence of activated brown adipose tissue (ABAT) has been associated with a reduced risk of obesity in adults. We aimed to investigate whether the presence of ABAT in patients undergoing (18)F-FDG PET/CT examinations was related to blood lipid profiles, liver function, and the prevalence of non-alcoholic fatty liver disease (NAFLD).

Methods: We retrospectively and prospectively analysed the (18)F-FDG PET/CT scans from 5,907 consecutive patients who were referred to the Nuclear Medicine Department of the Marmara University School of Medicine from outpatient oncology clinics between July 2008 and June 2014 for a variety of diagnostic reasons.
