本研究调查了代谢活性脂肪组织（棕色脂肪）和非活性脂肪组织（白色脂肪）之间由于密度变化而导致的CT亨氏单位（HU）差异。分析了101例儿童和青少年患者的PET/CT数据。确定代谢活性和非活性脂肪组织的区域，并测量标准摄取值（SUV）和HU。活性棕色脂肪的HU比非活性脂肪（−62.4±5.3 vs −86.7±7.0）更积极（p<0.001），并且在男性和女性中均观察到差异。
This study investigates differences in CT Hounsfield units (HUs) between metabolically active (brown fat) and inactive adipose tissues (white fat) due to variations in their densities. PET/CT data from 101 pediatric and adolescent patients were analyzed. Regions of metabolically active and inactive adipose tissues were identified and standard uptake values (SUVs) and HUs were measured. HUs of active brown fat were more positive (p<0.001) than inactive fat (−62.4±5.3 versus −86.7±7.0) and the difference was observed in both males and females.
