摘要
LC(集总常数)是FDG(氟代脱氧葡萄糖)与葡萄糖的代谢率之比。不仅在不同的组织中LC有不同的值,而且在同一组织中,生理状态的变化也会引起LC变化。重点介绍了几种组织中的LC值以及LC的计算方法。另外,还介绍了几种获取输入函数的简化方法。
Lumped constant (LC) is the ratio of FDG metabolism ratio to glucose metabolism ratio. There is different LC in the different tissue, and the different physiologic condition in a tissue can also result in the different LC. In this paper we summarize LC values in several tissue and the method to calculation them, and introduce several simple method to get input function.
