目的:探讨剥夺睡眠和睡眠诱发试验脑磁图(MEG)对癫的诊断价值。方法:对56例临床确诊的癫病人剥夺睡眠之后进行睡眠诱发的MEG检查,比较在清醒期和睡眠期样放电的出现率。结果:睡眠和剥夺睡眠状态MEG的异常率都有提高,还可增加棘波的检出率,但各种癫发作类型之间的棘波检出率比较差异无统计学意义。结论:样放电检出率的提高不仅与诱发方法有关,而且与癫的发作类型有关。
Objective: To investigate the diagnostic value of magnetic resonance imaging (MEG) in deprivation of sleep and sleep-induced test on epilepsy. Methods: 56 cases of clinically diagnosed epileptic patients were deprived of sleep after sleep-induced MEG examination, during awake and sleep-like discharge rate. Results: The abnormal rate of MEG in both sleep and sleep deprivation increased, but also increased the detection rate of spikes, but there was no significant difference in the detection rate of spikes between various types of epileptic seizures. Conclusion: The detection rate of like discharge is not only related to the induction method, but also related to the type of epilepsy.
