【摘要】 目的:研究脑电图(EEG)和磁共振成像(MRI)在病毒性脑炎的早期诊断和预后评价中价值。方法:对临床确诊的52例病毒性脑炎的EEG和MRI表现进行观察。结果:一周内EEG异常率92.3%;双侧θ波节律者预后较好;电静息及爆发棘慢波间断电静息者预后可能临床死亡;MRI一周内阳性率61.5%:MRI动态改变与临床表现不一致。结论:MRI有助于病毒性脑炎的诊断;EEG对早期诊断及预后评价优于MRI。更多还原

【Abstract】 Objective: Our purpose was to study the value of electroencephalography (EEG) and magnetic resonance imaging (MRI) in the early diagnosis and prognosis of virus encephalitis. Methods: We observed the EEG and MRI in 52 patients with virus encephalitis at the first time of hospitalization. Results: EEG was abnormal in 92.3% patients within7days. The patients with bilateral 6 wave rhythm might have nice prognosis. Patients with focal epileptic waves had epileptic sequel. Bioccipital electrical silence, one-side electrical silence and bursting spike, and slow-wave-interrupted electrical silence indicated the probability of clinical death. The MRI showed abnormalities in 32 patients including multiple or single lesions. The positive rate was 61.5% within 7 days. Conclusion: The MRI is useful for clinical diagnosis of virus encephalitis. The EEG in acute stage is superior to MRI in diagnosis and prognosis of virus encephalitis.更多还原
