CT和MRI诊断小儿病毒性脑炎的价值观察

Value of CT and MRI in the Diagnosis of Viral Encephalitis in Children

目的观察电子计算机断层扫描(CT)和磁共振成像(MRI)诊断小儿病毒性脑炎的价值。方法选取2018年4月至2019年4月于我院住院的95例病毒性脑炎患儿,所有患儿均行CT和MRI检查,比较两种方法的诊断效能。结果95例病毒性脑炎患儿,CT检出68例患儿异常,其中轻度异常22例,中度异常35例,重度异常11例,阳性检出率为71.58%;经MRI诊断结果显示,检出90例患儿异常,其中轻度异常26例,中度异常49例,重度异常15例,阳性检出率为94.74%,MRI诊断异常检出率明显高于CT诊断(P<0.05);经CT诊断结果显示,54.74%(52/95)患儿为多发病灶,16.84%(16/95)为单发病灶;经MRI诊断结果显示,70.53%(67/95)患儿为多发病灶,24.21%(23/95)为单发病灶,MRI诊断病灶检出率明显高于CT诊断(P<0.05);随着小儿病毒性脑炎疾病进展,CT和MRI诊断的敏感度呈升高趋势,MRI诊断的敏感度明显大于CT诊断(P<0.05)。结论CT和MRI均可用于诊断小儿病毒性脑炎,MRI诊断敏感性更高。

Objective To observe the value of computed tomography(CT)and magnetic resonance imaging(MRI)in the diagnosis of viral encephalitis in children.Methods Ninety-five children patients with viral encephalitis hospitalized in our hospital from April 2018 to April 2019 were selected.All patients underwent CT and MRI examination.The diagnostic efficacy of the two methods was compared.Results A total of 68 abnormal cases were diagnosed by CT among the 95 children patients with viral encephalitis,including 22 cases of mild abnormalities,35 cases of moderate abnormalities and 11 cases of severe abnormalities,with positive detection rate of 71.58%.According to MRI diagnosis,90 abnormal cases were detected including 26 cases of mild abnormalities,49 cases of moderate abnormalities and 15 cases of severe abnormalities,with positive detection rate of 94.74%.The abnormal detection rate of MRI was significantly higher than that of CT(P<0.05).CT diagnosis showed 54.74%(52/95)of children patients were multiple lesions and 16.84%(16/95)were single lesions.MRI diagnosis showed that 70.53%(67/95)children patients were multiple lesions and 24.21%(23/95)were single lesions.The lesion detection rate of MRI was significantly higher than that of CT(P<0.05).With the progress of viral encephalitis in children patients,the sensitivity of CT and MRI showed a increasing trend,and the sensitivity of MRI was significantly higher than that of CT(P<0.05).Conclusion both CT and MRI can be used to diagnose viral encephalitis in children.MRI has higher sensitivity.
