【摘要】：目的探讨脑CT检查对儿童中枢神经系统感染的诊断效果,结合临床实际分析其应用价值。方法选取2015年1月-2016年4月儿童内科收治确诊的中枢神经系统感染患儿48例为研究对象,均排除患有严重心肝肾器质性病变和免疫血液系统疾病,入院后分别行电子计算机断层扫描(CT)、磁共振成像(MRI)检查,重点观察中枢神经系统感染患儿脑CT检查的影像表现,以临床综合确诊结果为金标准并与MRI检查结果比较,观察脑CT检查的诊断效果,综合分析其临床应用价值。结果 48例中枢神经系统感染患儿中CT检查确诊病毒性脑炎15例、结核性脑膜炎8例、脑囊虫病5例、化脓性脑膜炎4例,总确诊率为66.67%,MRI检查病毒性脑炎20例、结核性脑膜炎10例、脑囊虫病6例、化脓性脑膜炎5例,总确诊率为85.42%,两者比较差异有统计学意义(P0.05);CT对25例细菌性感染确诊率43.48%(10/23),低于MRI检查95.65%(22/23),比较差异有统计学意义(P0.05),CT、MRI检查23例病毒性感染患儿确诊率分别为88.00%(22/25)、76.00%(19/25),比较差异无统计学意义。结论 CT、MRI均是临床检查中枢神经系统感染的重要手段,MRI诊断效果相对更优;CT在临床应用中检查可根据诊断需要借助MRI检查,优化诊断效果。
[Abstract]:Objective to investigate the diagnostic effect of brain CT on central nervous system infection in children. Methods from January 2015 to April 2016, 48 children with CNS infection diagnosed in pediatric medicine department were selected as the research objects. All patients were excluded from severe heart, liver and kidney diseases and immune and blood system diseases. After admission to hospital, CT and MRI were performed separately, and the imaging manifestations of brain CT in children with central nervous system infection were observed emphatically. The diagnostic effect of CT examination was observed and its clinical application value was analyzed. Results 15 cases of viral encephalitis were diagnosed by CT in 48 children with central nervous system infection. There were 8 cases of tuberculous meningitis, 5 cases of cerebral cysticercosis, 4 cases of suppurative meningitis. The total diagnosis rate was 66.67% MRI in 20 cases of viral encephalitis, 10 cases of tuberculous meningitis, 6 cases of cerebral cysticercosis and 5 cases of suppurative meningitis. The total diagnostic rate was 85.42, and the difference was statistically significant. The diagnostic rate of 25 cases of bacterial infection by P0.05CT was 43.48 / 10 / 23, which was lower than that of MRI (95.65 / 22 / 23). The difference was statistically significant (P < 0.05). The diagnostic rate of 23 children with viral infection was 88.0022 / 2576.00 / 19 / 25, respectively, and the difference was significant (P < 0.05). Conclusion CT MRI is an important method in the diagnosis of central nervous system infection. The diagnostic effect of CT is better than that of CT in clinical application. According to the need of diagnosis, MRI can be used to detect the infection of central nervous system. Optimize diagnostic effect.
