术前准确的致痫灶定位,是癫痫外科治疗的关键,近几年来发展起来的脑磁图(ＭＥＧ)致痫灶定位技术,能将捕促到的瞬时磁信号与三维ＭＲＩ解剖图融合,从而精确确定致痫灶的解剖部位,有极高的时间和空间分辨率,同时由于磁信号穿过头皮及颅骨等解剖结构时不会发生畸变,所以ＭＥＧ定位致痫灶较其它功能检查具有更高的准确性。ＭＥＧ检查的阳性率明显高于ＥＥＧ/ＶＥＥＧ和ＰＥＴ/ＳＰＥＣＴ,且与Ｅｏ有极高的符合率,同时它在致痫灶功能区定位和癫痫术后复发再次手术前评估方面有重要意义。
Precise preoperative localization of the epileptogenic zone is the key to the surgical treatment of epilepsy. In recent years, the development of the epileptic foci of MEG has enabled the fusion of the captured transient magnetic signal with the three-dimensional MRI anatomy. So as to accurately determine the anatomic site of epileptogenic lesions, there is a very high time and spatial resolution, and because the magnetic signal through the scalp and skull and other anatomical structures will not be distorted, so MEG positioning epileptic lesions than other functional tests have more High accuracy. The positive rate of MEG examination was significantly higher than that of EEG / VEEG and PET / SPECT, and it had a very high coincidence rate with Eo. Meanwhile, it was of great significance in the preoperative evaluation of functional areas of epileptic foci and recurrence of epilepsy.
