摘要:

［目的］对比无症状脑梗塞脑电图(EEG)与头颅磁共振(MR)扫描两者之间的符合率。［方法］对204例正常体检者全部进行EEG及MR检查。［结果］发现无症状脑梗塞21例，其中腔隙性梗塞19例，脑叶梗塞2例。高血压及糖尿病性微血管病是主要病因。［结论］ EEG “阳性率”与头颅MR扫描结果比较，两者符合率为62.5%。提示EEG对无症状脑梗塞的粗筛具有重要意义。

Abstract:

［Objective］ To compare the coincidence rate between the EEGs(electroencephalo- graph) from patients with symptomless cerebral infarction and their head MRs(magnetic resonance). ［Methods］ 204 cases of normal examinees are all examined with EEG and MR. ［Results］21 of the 204 cases have symptomless cerebral infarction, of whom 19 have lacuna infarction and 2 have lobe infarction. The main reason for symptomless cerebral infarction is hypertension, and microangiopathy caused by diabetes mellitus. ［Conclusion］Compared the EEG positive rate and the results of the head MRs, their coincidence rates are both 62.5%, showing that EEG means much to the riddle of symptomless cerebral infarction.
