Interictal EEG spike field potentials by visual and quantitative EEG analysis were studied in 17 patients with intractable localization related epilepsy. Quantitative EEG analysis was done using commercially available window based computer program (Focus) that displayed digitally acquired EEG data and performed spline mapping. Routine EEG localized 20 spikes. Fourteen spikes had excellent congruence between manual and computer generated mapping, 6 had good congruence, and 1 had fair congruence. This study clearly proves the usefulness of spline interpolation mapping technique in localizing and characterizing the epileptiform focus.
通过视觉和定量脑电图分析，对17例难治性局灶性相关性癫痫患者的发作间期脑电图棘波场电位进行了研究。定量脑电图分析使用市售的基于窗口的计算机程序（Focus）进行，该程序显示数字采集的脑电图数据并进行样条映射。常规脑电图定位出20个棘波。14个棘波在手动和计算机生成的映射之间具有极佳的一致性，6个具有良好的一致性，1个具有尚可的一致性。本研究清楚地证明了样条插值映射技术在癫痫样病灶定位和特征描述中的有用性。
