病毒性脑炎早期诊断的磁共振成像与脑电图比较研究

COMPARATIVE STUDY OF VIRAL ENCEPHALITIS EARLY DIAGNOSIS BY MAGNETIC RESONANCE IMAGING AND ELECTROENCEPHALOGRAM

目的探讨病毒性脑炎早期磁共振成像和脑电图表现,并对其在病毒性脑炎早期诊断中的临床价值进行比较。方法选择2008-2011年收治的病毒性脑炎患者98例的磁共振成像和脑电图表现行动态观察,并将结果与实验室检查结果进行比较。结果所有患者入院后均在短期内行磁共振成像和脑电图检查,其中磁共振成像异常50例,异常率为51.0%,78例患者出现脑电图异常,异常率为79.6%,2种方法联合诊断后异常率为95.9%,显著高于单一方法使用(P<0.05)。结论脑电图检查在病毒性脑炎早期诊断及鉴别诊断中比磁共振成像检查更具有价值,且2种方法联合使用可显著提高诊断敏感性,值得临床推广。

Objective To compare the early diagnosis value of virus encephalitis by magnetic resonance imaging（MRI） and electroencephalogram（EEG）. Methods Ninety -eight patients with virus encephalitis were observed by MRI and EEG, and the results were compared. ＂Results The abnormal rate of MRI and EEG was 51.0% and 79.6% respectively, and there was significantly difference between MRI and EEG（P 〈0.05） ,however,the abnormal rate of combination of two methods was 95.9% ,which was significantly higher than anyone used alone （ P 〈 0.05 ）. Conclusion EEG is more valuable than MRI in early diagnosis of virus encephalitis, and the combination of two ways can significantly improve the diagnostic sensitivity.
