Magnetoencephalography combines the attributes of real-time millisecond temporal resolution with precise anatomic localization. In addition to characterizing spontaneous epileptiform discharges and slow wave activity, magnetoencephalography may be used to map sensorimotor, auditory, and visual functions. Magnetoencephalography functional data are registered to three-dimensional magnetic resonance imaging to provide a useful way to analyze the relationship of structure to function and to assist in surgical planning. Magnetoencephalography is noninvasive and can be done with rapid turn-around time, but it is expensive and is not optimal for all brain areas or functions. Future integration and cross-analysis of magnetoencephalography with other functional mapping modalities will likely prove to be complementary and of even greater use.
脑磁图结合了实时毫秒级时间分辨率和精确的解剖定位特性。除了表征自发性癫痫样放电和慢波活动外，脑磁图还可用于绘制感觉运动、听觉和视觉功能图。脑磁图功能数据与三维磁共振成像进行配准，以提供一种分析结构与功能关系并辅助手术规划的有用方法。脑磁图是非侵入性的，且可以在短时间内完成，但它成本高昂，并非对所有脑区或功能都最为适用。未来脑磁图与其他功能映射方式的整合和交叉分析可能会被证明具有互补性且用途更大。
