Cerebral glucose metabolic mapping using positron emission tomography (PET) and 2-[18F]fluoro-2-deoxyglucose (FDG) has been extensively studied in the epilepsies. Regions of interictal glucose hypometabolism are highly associated with cerebral sites of seizure generation-propagation in focal epilepsies. The volume of reduced glucose metabolism is often widespread and even bilateral in focal epilepsies, although ictal onset zones typically are located at the sites of most severe hypometabolism within a larger volume of hypometabolism.
使用正电子发射断层扫描（PET）和2-[18F]氟-2-脱氧葡萄糖（FDG）进行的脑葡萄糖代谢图谱在癫痫研究中已得到广泛应用。发作间期葡萄糖代谢减低区域与局灶性癫痫发作的起始-传播脑区高度相关。在局灶性癫痫中，葡萄糖代谢减低的区域通常广泛存在，甚至双侧受累，尽管发作起始区通常位于更大范围代谢减低区内代谢最严重的部位。
