The influence of MR on the EEG and neuropsychological functions was investigated. An EEG was done in 8 of 20 patients before and after 0.5 Tesla MRI. Computerized EEG analysis showed no significant differences in respect of the dominant frequency and the power spectrum. The memory functions of 12 patients were investigated by clinically proven neuropsychological tests before and after MRI (0.5 and 1.5 tesla). The results demonstrated no measurable influence of MRI on cognitive functions.
研究了磁共振成像（MR）对脑电图（EEG）和神经心理功能的影响。20名患者中有8名在0.5特斯拉磁共振成像检查前后进行了脑电图检查。计算机化脑电图分析显示，在主频和功率谱方面没有显著差异。12名患者的记忆功能在磁共振成像（0.5和1.5特斯拉）前后通过临床验证的神经心理测试进行了研究。结果表明，磁共振成像对认知功能没有可测量的影响。
