摘　　要：18 F-FDG PET／CT临床应用越来越广泛，其在恶性肿瘤的诊断、分期、疗效评价及预后评估中作用显著。肝脏作为糖代谢的主要器官，常作为临床图像质量控制及疾病诊断的参考对象，然而肝脏的18 F-FDG摄取状况受多种生理状态、潜在病理因素、显像技术及个体间差异等因素的影响，而且不同校正方法对SUV的影响亦不容忽视。笔者就影响肝脏18 F-FDG摄取的多种因素及不同校正方法对SUV的影响加以综述，以期为临床18 F-FDG PET／CT图像解读提供帮助。18 F-FDG PET/CT has been increasingly used in diagnosis, staging, treatment response assessment and prognosis prediction of malignant tumors. As the main organ of carbohydrate metabolism, liv-er is commonly taken as reference organ in disease diagnosis and imaging quality control. Hepatic FDG up-take in healthy people is affected by various physiological, potential pathological and imaging technical fac-tors, as well as inter-individual variation. Besides, variation of SUV caused by different calibrating methods cannot be neglected. The factors that affecting hepatic FDG uptake based on findings in recent studies are summarized in this review.
