Abstract
Magnetoencephalography (MEG) has a long history of development for the application of epilepsy. Technical and clinical validation of spike source estimation has been demonstrated in most partial epilepsies. The question that needs to be clarified concerns clinical value: Do identification and localization of epileptiform discharges play an important role in the determination of epilepsy localization for surgery? EEG is the mainstay in the investigation of seizure disorders and will remain so because it alone possesses the attribute of long-term recordings that can capture seizures. In contrast, MEG has the unique capability of nearly instantaneous high-resolution recording, with detection sensitivity and spike localization precision beyond that of EEG. Do these distinctions matter from a clinical standpoint?
摘要
脑磁图（MEG）在癫痫的应用中有很长的发展历史。在大多数部分性癫痫中，已经证明了尖峰源估计的技术和临床验证。需要澄清的问题是临床价值：癫痫样放电的识别和定位是否在手术定位癫痫中起重要作用？EEG 是癫痫发作障碍研究的主要手段，而且仍将如此，因为它独自具有能够捕获发作的长期记录的属性。相比之下，MEG 具有近乎瞬时的高分辨率记录的独特能力，具有优于 EEG 的检测灵敏度和尖峰定位精度。从临床角度来看，这些区别重要吗？
