摘要
目的研究病毒性脑炎的临床表现及影像学特点。方法对2007年-2008年收治的14例病毒性脑炎患者的临床表现及影像学资料等原始资料进行回顾性分析。结果病毒性脑炎的磁共振成像(MRI)主要表现为长T1,T2信号,特征性的MRI表现多出现在发病后2-4周。结论头颅MRI在早期诊断病毒性脑炎方面明显优于CT检查,但头颅MRI检查只能协助诊断病毒性脑炎,多次头颅MRI阴性也不能排除病毒性脑炎的诊断。
Objective To investigate the clinical manifestation and imaging characteristics of the viral encephalitis. Methods The clinical data of 14 patients with viral encephalitis was analyzed retrospectively. Resuits Magnetic resonance imaging（MR1） of viral encephalitis mainly performed for long T1,T2 signal, Characteristic findings of MRI appeared in 2-4 weeks after the onset of disease. Conclusion MRI is surperior to CT in detecting early lesions with viral encephalitis, but MRI can only help diagnose the viral encephalitis, the negative results of MRI for several times also cannot exclude the viral encephalitis.
