功能成像的小鼠棕色脂肪组织(BAT)的方法进行了说明,冷刺激BAT摄取18F-脱氧葡萄糖(FDG)的非侵入性评估与标准化的micro-PET/CT协议。这种方法的鲁棒性和敏感的检测BAT活动在小鼠模型中的差异。

该程序的总体目标是使用标准化的显微 PET CT 方案无创测量活小鼠的棕色脂肪组织活性。这是通过首先将动物置于 4 摄氏度的冷处理中 4 小时以诱导棕色脂肪组织活动来实现的。接下来注射氟,注射 18 FTG,并将动物在 4 摄氏度下再孵育 1 小时以实现活性摄取。

然后使用小动物专用成像系统进行一系列显微 CT 和显微 PET 成像。最后,使用成像后处理软件,将获取的宠物图像与 CT 图像进行共配,然后分析 FDG 在肩胛间蝙蝠区域的摄取情况,以呈现蝙蝠的活动。棕色脂肪组织在骨骼哺乳动物和成人的能量消耗和产热中起主要作用。
