【摘要】 目的:通过¹⁸F-FDG PET/CT显像9 144例被检查者,探讨棕色脂肪在成人体内存在与分布状况,以及棕色脂肪FDG摄取与年龄性别、身体成分、季节的关系。方法:回顾性分析9 144例被检查者PET/CT结果,其中男性5 876例,女性3 268例。受检者空腹6 h以上,行PET/CT检查。结果:117例被检查者发生棕色脂肪FDG摄取,占被检查者总数的1.28%;其中男性35例,女性82例,出现棕色脂肪摄取的人数有明显季节差异,寒冷季节高于较温暖季节。结论:在临床实验条件下,发现棕色脂肪FDG摄取较易发生于年轻女性及体重指数偏低的患者中,在较寒冷季节进行检查也会显著提高该现象的发生率。推测棕色脂肪实验条件下,阳性检出率将会更高。更多还原

【Abstract】 Objective: It is to evaluate brown adipose tissue( BAT) uptake patterns and its relationships with age,gender, physical condition and season differences, with the tracer compound18F- FDG by positron emission tomography / computer tomography( PET / CT) imaging. Methods: The study analyzed 9 144 cases who were scanned( 3 268 female and 5 876 male). They fasted at least 6h before the PET scan. Results: Of the 9 144 scans,117 cases( 1. 28%; 35 male and 82 female) possessed brown fat. The cases with brown fat were younger and thinner than the cases without it; the incidence was highest in cool season in the whole group of the cases. Conclusions: FDG uptake in BAT occurs particularly in younger female patients and those with lower body mass index values. The incidence of brown fat is clearly increased during the cooler period of the year. If experimental conditions are controlled,more cases may be found.更多还原
