摘要
目的 :探讨偶极子定位法 (DL M)对癫痫痫灶定位的价值。方法 :对 133例癫痫病人进行 DL M和 CT/MRI检查 ,部分病人行单光子发射计算机断层扫描 (SPECT)和正电子发射断层扫描 (PET)检查 ;12 0例手术病人行皮层或深部电极验证并对其结果进行对比分析。结果 :DL M检查与术中电极结果一致 ,且精确度高 (<1cm)、特异性好。结论 :DL M是一种新型的无创伤癫痫痫灶定位方法 ,对局限性癫痫样波 DL M定位明显优于影像学方法。
Objective:To investigate the value of epileptic foci localization by dipole localization method(DLM) Method:133 patients with epilepsy were examined by DLM and CTM/RI,single photon emission computed tomography (SPECT) and positron emission tomography (PET) were done in some cases of this group;120 surgical patients were checked up by cortical or deep electrode in operation and the results were compared.Result:The localization by DLM was identical with that by operative electrode,it showed well high degree of accuracy (<1cm) and specificity.Conclusion:DLM is a new type method of epileptic foci localization with non-invasion.It was suggested that DLM localization would be obviously superior to neuroimage localization.\;
