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PET/CT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 18F-FDG PET/CT in epileptogenic zone localization.Methods Tirty-two patients with epilepsies were studied with interictal 18F-FDG PET/CT cerebral imaging,and all of them had scalp EEG,CT or MRI results for comparision.Results The sensitivity of 18F-FDG PET/CT was 90.6%,27 patients(84.5%) showed focal hypometabolism,2 patients(6.3%) showed focal hypermetabolism 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 epileptic foci.
