摘要
目的探讨脑磁图在神经外科中的定位价值。方法本组 26例神经外科患者,男18例,女8例,术前均行脑电图(Electroencephalogram, EEG)检查和影象学检查,同时做了脑磁图(Magnetoencephalograph,MEG)检查。所有患者手术均在MEG指导下进行,术中加用皮层脑电图(Electrocorticography, EcoG)监测。结果 26例患者均能通过MEG进行术前致痫灶与功能定位,其阳性率明显高于EEG和影象学检查。术后复查EEG,25例患者较好,短期随访(1～3月)患者癫痫发作完全消失。结论 MEG是神经外科中的一项术前致痫灶定位和功能保护的有效检查方法。
Objective To explore the significance of MEG in the localization of neurosurgery, Method There were 26 patients in this group, with male 18 and female 8. All the patients underwent electroencephalography(EEG)and imaging examination before operation. Meanwhile they had MEG examination, Under the guidance of MEG, all the patients were operated on. During the operation, electrocorticography(EcoG)was performed. Result MEG examination showed that there was abnormality in all patients. The positive rate was higher than EEG and imaging examination. At the same time the result of MEG agreed with EcoG monitoring. The postoperative EEG examination revealed that 22 patients had good result,The short-time follow-up showed that complete seizurecessation was achieved in 25 patients. Conclusion MEG is an effective location method of epileptogenic lesion and function preservation before operation.
