摘要
棕色脂肪组织是存在于正常人体内的一种脂肪组织,具有特殊的生理作用。棕色脂肪在被激活产热过程中,会引起^18F-氟脱氧葡萄糖(^18F—FDG)的摄取增多,造成PET影像呈现多种形式分布的放射性浓聚。掌握棕色脂肪组织的^18F-FDG分布规律、特点及其鉴别方法,将有助于提高肿瘤^18F—FDGPET的诊断特异性。
Brown adipose tissue (BAT) is a kind of normal tissue in healthy subject, which has unique physiological function. BAT will accumulate higher ^18F-fluorodeoxyglucose(^18F-FDG) in the process of its being excited, and presents variety of radioactive accumulation while performing PET scan. It will benefit improving diagnostic specificity of ^18F-FDG PET imaging to master the regular patterns, features of uptaking ^18F-FDG and differential methods.
