摘　　要：目的探究小儿病毒性脑炎诊断中头颅MRI诊断的临床意义。方法选择我院2017年1月至2021年1月期间收治84例病毒性脑炎患儿作为研究对象,对患儿进行CT检查以及头颅MRI检查,比较诊断符合率、灵敏度、特异度,病灶检出情况、不同病情患儿预后效果。结果在小儿病毒性脑炎诊断中,头颅MRI诊断符合率、灵敏度、特异度分别为98.81%、98.72%、100.00%,与CT诊断符合率、灵敏度、特异度86.90%、89.74%、50.00%比较,差异显著(P<0.05);MRI诊断结果单发病灶概率8.97%、多发病灶概率89.74%,与CT诊断结果单发病灶概率1.28%、多发病灶概率88.46%比较,单发病灶检出率差异显著(P<0.05)。MRI诊断结果显示轻度异常、中度异常、重度异常病例数分别为41例、31例、5例,病情越严重感染控制时间越长,且后遗症发生率越高。结论在小儿病毒性脑炎诊断中应用头颅MRI,可获得较高的诊断准确率,病灶检出率高,同时可对感染控制时间及后遗症发生率进行预测,值得应用。Objective To explore the clinical significance of head MRI in the diagnosis of viral encephalitis in children.Methods 84 cases of children with viral encephalitis admitted to our hospital from January 2019 to January 2021 were selected as the research subjects.CT examination and head MRI examination were performed on the children,and the diagnostic coincidence rate,sensitivity,specificity,detection of lesions and prognosis of children with different conditions were compared.Results In the diagnosis of pediatric viral encephalitis,the coincidence rate,sensitivity and specificity of head MRI were 98.81%,98.72%and 100.00%,respectively,compared with CT diagnosis of 86.90%,89.74%and 50.00%,the difference was significant(P<0.05).MRI results showed that the probability of single lesion was 8.97%and the probability of multiple lesions was 89.74%.Compared with CT results,the probability of single lesion was 1.28%and the probability of multiple lesions was 88.46%,and the detection rate of single lesion was significantly different(P<0.05).MRI results showed that the number of cases with mild,moderate and severe abnormalities was 41,31 and 5,respectively.The more severe the disease was,the longer the infection control time was,and the higher the incidence of sequelae.Conclusion The application of cranial MRI in the diagnosis of viral encephalitis in children can obtain high diagnostic accuracy,high detection rate of lesions,and can predict the time of infection control and the incidence of sequelae,which is worthy of application.
