颅脑CT阴性的难治性复杂部分癫痫患者发作间期的EEG和SPECT

Obervation of interictal brain EEG and SPECT in refractory complex partial epileptic patients whose brain CT was normal

目的 比较颅脑CT阴性的难治性复杂部分癫痫患者EEG和SEPCT的检查结果。方法 12例难治性复杂部分癫痫患者均采用脑电图仪行EEG检查 ,99Tc HM PAO行SPECT检查。结果 EEG和SPECT脑显像异常所见基本一致者为 5例 ,不一致者为 7例。其中EEG呈弥漫性异常 5例 ,SPECT脑显像均发现病灶。结论 SPECT脑显像对颅脑CT阴性的难治性复杂部分癫痫的病灶检出率要高于EEG。

Objective: To compare the results of interictal brain EEG(electroencephalography) with SPECT(single photon emission computed tomography) in refractory complex partial epileptic patients whose brain CT scans were normal. Methods: 12 refractory complex partial epileptic patients were observed with interictal brain EEG and SPECT. Results: All patients showed abnormally on interictal brain EEG and SPECT. The localization of epileptic foci was the same in 5 patients and different in 7 patients. Interictal brain SPECT 5 patients whose EEG showed epileptic foci in were abnormal in all lobes. Conclusion:The study suggests that the detection rate of epileptic foci though SPECT imaging is relatively high compared with EEG recording.
