摘要
目的探讨正电子药物18F氟代脱氧葡萄糖（18F-FDG）在正电子发射计算机（断层PET／CT）脑显像致痫灶定位中的应用。方法对32例癫痫患者行18F-FDG脑三维PET／CT显像，将其定位结果与头皮脑电图（EEG）、颅脑CT或MRI结果进行比较。结果PET／CT阳性检出率为90．6％（29／32），其中低代谢灶27例，高代谢灶2例，正常3例；EEG阳性检出率为65．6％（21／32），常规脑部CT或MRI阳性检出率为31．0％（10／32）。结论18F-FDG在PETJCT脑显像中对癫痫的定位诊断有较高的灵敏性和准确性。
Objective To discuss the application of 18 F-FDG PET/CT in epileptogenie zone localization. Methods Tirty-two patients with epilepsies were studied with interietal 18F-FDG PET/CT cerebral imaging, and all of them had scalp EEG, CT or MRI results for eomparision. Results The sensitivity of 18F-FDG PET/CT was 90. 6% ,27 patients（84.5% ） showed focal hypometabolism,2 patients（6. 3% ） showed focal hypermetabohsm and rest 3 patients （9. 4% ） had negative result. The sensitivity of EEG was 65.6% （21/32）, the sensitivity of CT and MRI was 31.0% （10/32）. Conclusion 18F-FDG PET/CT was a sensitive and accurate image modality in the localization of epileptle loci.
