摘要

正电子发射断层扫描联合18f -氟脱氧葡萄糖(18F-FDG)计算机断层扫描(PET/CT)在癌症患者的管理中起着重要作用,主要用于肿瘤的初级分期、治疗效果评价和疾病复发的检测。由于18F-FDG摄取的非特异性,放射科医生必须熟悉放射性药物的生理和非典型分布。患者不适当的研究准备和/或服用某些药物可导致18F-FDG分布异常。我们的临床病例表明,在长期使用糖皮质激素治疗的儿童中,白色脂肪组织中出现了非典型的18F-FDG摄取。

Atypical Uptake of 18FDG in White Adipose Tissue During PET/CT in Children
Positron emission tomography combined with computed tomography (PET/CT) with 18F-fluoro-deoxyglucose (18F-FDG) plays an important role in the management of cancer patients and is mainly used for primary staging, evaluation of treatment response and detection of disease recurrence. Due to non-specific nature of 18F-FDG uptake, a radiologist must be familiar with both physiological and atypical distribution of radiopharmaceuticals. Inappropriate patient preparation for the study and/or taking certain drugs can lead to abnormal 18F-FDG distribution. Our clinical case demonstrates an atypical uptake of 18F-FDG in white adipose tissue in a child treated with glucocorticoids for a long time.
