脑体层摄影(TEG)对癫痫的诊断有重要的实用价值。过去对癫痫的诊断是依靠病史、临床检查及常用的辅助检查法(脑电图、闪烁照相、血管造影及气脑造影),仅40%的病例能确定病因,加用TEG后,确定病因的比例接近55%。同时,TEG还能看到其它检查法所遗漏的病变。作者用此法检查500例患者,研究结果可从两个方面来看。 TEG has important practical value in the diagnosis of epilepsy. Past diagnosis of epilepsy depends on the history, clinical examination and commonly used auxiliary examination (EEG, scintigraphy, angiography and pneumoperitoneum), only 40% of the cases to determine the cause, plus TEG, to determine the cause The ratio is close to 55%. At the same time, TEG can also see the lesions missed by other examinations. The authors examined 500 patients with this method, the results of which can be viewed from two aspects.
