18 F 2 脱氧葡萄糖 (FDG)显像在肿瘤诊断中的应用已成为核医学和肿瘤学的热点[1 4] 。FDG为葡萄糖的类似物 ,进入组织后能象葡萄糖一样被细胞摄取 ,因而可以反映组织对葡萄糖的需要量。与正常组织细胞相比 ,恶性肿瘤细胞对葡萄糖的摄取和代谢增加 ,这就为FDG显像诊断恶性肿瘤
The application of 18 F 2 deoxyglucose (FDG) imaging in the diagnosis of tumors has become a hot spot in nuclear medicine and oncology [14]. FDG is an analogue of glucose that enters the tissue and is taken up by cells like glucose, thus reflecting the tissue’s glucose requirements. Compared with normal tissue cells, malignant cells uptake of glucose and increased metabolism, which FDG imaging for the diagnosis of malignant tumors
