摘要
18F-FDG(18F-氟代脱氧葡萄糖)PET显像是依靠不同组织对18F-FDG的吸收差异来完成的,18F-FDG在肿瘤中的摄取增高与肿瘤的代谢及增殖情况、病理分级、分化程度、细胞的增生活性、倍增时间等生物学特性密切相关。进一步研究FDG吸收机制,将有助于对肿瘤的生物学特性更深一步的了解。
F-FDG( 18 F-fluorodeoxyglucose)PET imaging depends on different uptake of 18 F-FDG in different tissues.The uptake of 18 F-FDG in tumor tissue correlates with tumor's biologic behavours,such as metabolism,proliferating,pathologic stage,differentiation,the proliferating acitivity of cells and double times.With more knowlegement of the mechanisms of 18 F-FDG uptake,we'll know more about tumour's biologic behavours.
