The purpose of this article is to review the physiology and describe the typical and atypical presentations of brown fat on (18)F-FDG PET.
The 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.
本文旨在回顾棕色脂肪的生理学，并描述其在（18）F-FDG PET上的典型和非典型表现。
FDG PET上棕色脂肪的存在有可能导致误诊及不必要的侵入性检查，可通过采取诸如确保患者保暖、在检查前减少棕色脂肪对FDG的摄取以及利用PET/CT融合成像将PET摄取与特定解剖位置相关联等措施来避免。
