Magnetoencephalography is a newly developed technology used for diagnostic and brain mapping imaging during the presurgical evaluation of patients with medically intractable epilepsy. It provides comprehensive localisation of an epileptogenic focus using simultaneous recordings from the entire brain surface. Magnetoencephalography and electroencephalography are considered complementary and confirmatory to one another. We present a patient with magnetic resonance imaging-negative, non-lesional, neocortical epilepsy. Magnetoencephalography was used for re-evaluation of the epileptogenic zone and this enabled subsequent surgical removal of the epileptic focus. The role of magnetoencephalography in epilepsy surgery is discussed in this report.
脑磁图是一种新开发的技术，用于在药物难治性癫痫患者的术前评估中进行诊断和脑成像。它通过对整个脑表面的同步记录，提供致痫灶的全面定位。脑磁图和脑电图被认为是相互补充和相互证实的。我们报告了一位磁共振成像阴性、非病变性、新皮层癫痫患者。脑磁图用于重新评估致痫区，并随后进行癫痫灶的手术切除。本报告讨论了脑磁图在癫痫手术中的作用。
