摘　　要：目的探究在诊断小儿病毒性脑炎时使用头颅MRI和CT应用价值。方法回顾性分析2016年1月~2018年12月74例在我院接受头颅MRI与CT检查病毒性脑炎患儿影像学资料。分析CT和MRI诊断病毒性脑炎影像学特点,比较CT和MRI诊断患儿病情分度、病灶情况。结果MRI诊断患儿病毒性脑炎阳性率显著高于CT(97.30%vs83.78%,P<0.05),MRI对额叶和颞叶部位病灶检出显著优于CT(P<0.05),对顶叶以及其他部位病灶检出差异不显著(P>0.05)。MRI对于病毒性脑炎患儿多发病灶诊断情况优于CT,差异比较具有统计学意义(P<0.05)。结论在小儿病毒性脑炎诊断时使用头颅MRI诊断价值较CT高,尤其是在对于额叶和颞叶部位病灶以及多发病灶上诊断优势更为明显。Objective To explore the application value of skull MRI and CT in the diagnosis of viral encephalitis in children.Methods The imaging data of 74 children with viral encephalitis who completed skull MRI and CT examinations in the hospital between January 2016 and December 2018 were retrospectively analyzed.The imaging features of CT and MRI for the diagnosis of viral encephalitis were analyzed.The degree of the disease and lesions diagnosed by CT and MRI were compared.Results The positive rate of viral encephalitis diagnosed by MRI was significantly higher than that by CT(97.30%vs 83.78%).The detection of lesions in the frontal and temporal lobe by MRI was significantly better than CT(P<0.05).There was no significant difference in the detection of lesions in parietal lobe or other sites between the two methods(P>0.05).The detection of multiple lesions in children with viral encephalitis by MRI was superior to that by CT(P<0.05).Conclusion The diagnostic value of skull MRI is higher than that of CT in the diagnosis of pediatric viral encephalitis,especially for diagnosis of lesions in frontal and temporal lobe and multiple lesions.
