Reversal of Hypermetabolic Brown Adipose Tissuein F-18 FDG PET Imaging

Abstract

FDG uptake in HBAT has been noted to occur more frequently in cold months and benzodiazepines have been proposed for its prevention. The use of these drugs is, in our experience, of limited value and may complicate patient care in both inpatient and outpatient populations. In this report, we describe considerable success by completely reversing HBAT in 9 of 10 sequential patients with simple core warming maneuvers, which obviate the use of benzodiazepines.
