为了了解对颅内病变诊断的可靠性,作者对初步诊断为肿瘤(原发性或继发性)或血管意外的病人进行了过锝酸钠Tc 99m脑扫描,在脑扫描的1～2天内检查脑电图,并对在脑扫描和脑电图检查后6周内死亡而作尸检的共78例进行了分析,以观察脑扫描、脑电图与尸检结果的关系和对病因的鉴别。 78例中,尸检有脑瘤及脑血管病变等异常者59例,脑电图有异常者56例,脑扫描有异常者45例;尸检正常者19例,脑电图正常者22例,脑扫描正常者33
In order to understand the reliability of the diagnosis of intracranial lesions, the authors conducted a sodium pertechnetate Tc 99m brain scan on patients initially diagnosed as having tumor (primary or secondary) or vascular accident, and within 1-2 days of brain scan A total of 78 patients who underwent autopsy for death within 6 weeks after brain scan and EEG examination were analyzed to observe the relationship between brain scan, EEG and autopsy findings, and their etiology. Among the 78 cases, 59 cases had abnormal autopsy with brain tumor and cerebrovascular disease, 56 with abnormal EEG, 45 with abnormal brain scan, 19 with normal autopsy, 22 with normal EEG, Normal scan 33
