The potential for clinical application of computed EEG topography (CET) has been known since 1978. However, studies relating to the focal brain lesions are few. We have studied 19 cases of acute stroke involving the cerebral hemispheres. CET and EEG were recorded as soon as possible, usually within 1-3 days of onset. Repeat maps were recorded at 1 wk. Symptoms, neurologic exam, routine EEG and CT scan were compared with the CET of power spectral and flash evoked potential data. Statistical criteria were also applied. Good correlation was noted between CET and EEG and CT. Occasionally, CET was noted to provide information beyond EEG or CT. These early studies suggest a potential utility for CET in the early diagnosis of stroke.
自1978年以来，人们就已经知道计算机脑电图地形图（CET）的临床应用潜力。然而，与局灶性脑损伤相关的研究却很少。我们研究了19例累及大脑半球的急性中风患者。尽快记录CET和脑电图，通常在发病后1至3天内进行。在1周时记录重复图谱。将症状、神经系统检查、常规脑电图和CT扫描与功率谱和闪光诱发电位数据的CET进行比较。还应用了统计标准。发现CET与脑电图和CT之间有良好的相关性。偶尔，发现CET能提供超出脑电图或CT的信息。这些早期研究表明CET在中风的早期诊断中具有潜在的应用价值。
