Magnetoencephalography (MEG) is a functional cerebral imaging technique that non-invasively records extracranial magnetic fields generated by the electrical activity of the brain. Magnetic source imaging (MSI) is a combination of MEG and coregistered magnetic resonance imaging (MRI) that is increasingly being used in the non-invasive presurgical evaluation of patients with refractory partial epilepsy to localize the magnetic correlate of interictal epileptiform discharges. This paper reviews the basics of MEG and MSI, briefly describes the characteristics of the MEG system installed at the ULB-Hôpital Erasme and then summarises the available data on the contribution of MSI to the presurgical work-up of refractory partial epilepsy.
脑磁图（MEG）是一种功能性脑成像技术，可无创记录由大脑电活动产生的颅外磁场。磁源成像（MSI）是MEG与配准的磁共振成像（MRI）的结合，越来越多地用于难治性部分性癫痫患者的无创术前评估，以定位发作间期癫痫样放电的磁相关物。本文回顾了MEG和MSI的基础知识，简要描述了安装在ULB-埃拉斯穆斯医院的MEG系统的特点，然后总结了关于MSI对难治性部分性癫痫术前检查贡献的现有数据。
