我们调查了：（1）EEG记录可以在MRI成像仪中成功地进行，（2）亚临床癫痫放电可以用于触发超快功能MRI图像，（3）在患者监测EEG时可以获得无伪影的功能MRI图像，以及（4）如此获得的功能MRI图像将显示与癫痫放电相关的局灶性信号增加。我们报告了我们的结果，在两个病人谁表现出局灶性较高的信号强度，反映了增加的局部血流量，在超快功能磁共振成像定时记录癫痫放电，而病人在成像仪和图像相比，不与放电。1例患者尽管有全身放电的临床和EEG病史，但仍显示局灶性增加。这种方法可能有潜力，以确定短暂的局灶性癫痫放电过程中激活的大脑区域。神经病学1996;47：89-93
We investigated whether: (1) EEG recordings could be successfully performed in an MRI imager, (2) subclinical epileptic discharges could be used to trigger ultrafast functional MRI images, (3) artifact-free functional MRI images could be obtained while the patient was having the EEG monitored, and (4) the functional MRI images so obtained would show focal signal increases in relation to epileptic discharges. We report our results in two patients who showed focally higher signal intensity, reflective of increased local blood flow, in ultrafast functional MRI timed to epileptic discharges recorded while the patients were in the imager and compared with images not associated with discharges. One patient showed a focal increase despite a clinical and EEG history of generalized discharges. This approach may have the potential to identify brain regions activated during brief focal epileptic discharges. NEUROLOGY 1996;47: 89-93
