脑干听觉诱发电位、脑电图、MRI及MSCT在诊断重症病毒性脑炎患儿中的应用

Application of Brainstem Auditory Evoked Potential,Electroencephalogram,MRI and MSCT in the Diagnosis of Children Patients with Severe Viral Encephalitis

目的探讨脑干听觉诱发电位(BAEP)、脑电图(EEG)、磁共振成像(MRI)及多层螺旋CT(MSCT)诊断重症病毒性脑炎(VE)患儿的价值。方法回顾性分析2016年7月~2018年7月我院收治的56例重症VE患儿的临床资料,均在入院2天内接受BAEP、EEG、MRI、MSCT检查。记录BAEP、EEG图形,对MRI、MSCT图像阅片并观察病灶位置、范围、数量、大小等影像学特征,比较MRI和MSCT对VE阳性检出率的差异。结果56例患儿均可见BAEP、EEG异常,阳性检出率为100%,MSCT对VE患儿的阳性检出率(75.00%)显著低于MRI(91.07%)(P<0.05)。结论BAEP和EEG诊断重症VE患儿的准确性较高,有特征性波形改变;重症VE患儿在MRI、MSCT图像上均有特征性表现,但MRI诊断准确性更高。

Objective To explore the value of brainstem auditory evoked potential(BAEP),electroencephalogram(EEG),magnetic resonance imaging(MRI)and multi-slice spiral CT(MSCT)in the diagnosis of severe viral encephalitis(VE).Methods The clinical data of 56 children patients with severe VE admitted to our hospital from July 2008 to July 2018 were retrospectively analyzed.The patients were given BAEP,EEG,MRI and MSCT within 2 days after admission.The BAEP and EEG patterns were recorded.The MRI and MSCT images were read and the imaging features of location,extent,number and size of lesions were observed.The positive detection rate of VE was compared between MRI and MSCT.Results The abnormalities of BAEP and EEG were found in 56 cases,and the positive detection rate was 100%.The positive detection rate of MSCT in children patients with VE was significantly lower than that of MRI(75.00%vs 91.07%)(P<0.05).Conclusion BAEP and EEG have high accuracy in diagnosing children patients with severe VE and have characteristic waveform changes.Children patients with severe VE have characteristic findings on MRI and MSCT images,but MRI has higher diagnostic accuracy.
