摘要
目的 探讨单光子断层扫描 (SPECT)、脑电图 (EEG)、核磁共振 (MRI)对致痫灶定位的价值。方法 对4 0例临床确诊的癫痫患者进行SPECT、MRI、EEG等检查 ,比较三种检查方法对致痫灶定位的准确性。结果 EEG(包括长程监测 )特异性异常 34例 ,具有定侧定位意义的 30例 ,定位率 75 % (30 / 4 0 ) ;SPECT在发作间歇期定位率为4 7% (19/ 4 0 ) ;MRI定位率为 2 5 % (10 / 4 0 )。EEG对致痫灶的定侧定位率明显高于SEPCT及MRI,组间差异有统计学意义 (Q =30 .1,P <0 .0 1)。结论 EEG在致痫灶定位方面是一种敏感、经济、便捷又安全的检查方法。
Objective To explore the value of SPECT,EEG and MRI in the localization of epileptogenic focus.Methods SPECT,EEG and MRI were performed in 40 patients with clinically diagnosed epilepsy and the results of the three methods in the localization of epileptogenic focus were compared and analyzed.Results The accurate rate of lateralization and localization of EEG (including long-term monitoring)was 75%; SPECT was 47% in interictal period; MRI was 25%. The localization rate of epileptogenic focus by EEG was significantly higher than SPECT or MRI (Q= 30.1,P< 0.01).Conclusions:EEG is be a sensitive,economic and convenient method for the localization of epileptogenic focus.Combined with SPECT and MRI,it is improve the accuracy for focus localization.
