摘　　要：目的研究CT及MRI在中枢神经感染患者中的诊断效果,应用MRI对中枢神经感染患者进行诊断的可靠性提供依据。方法选取2013年7月-2014年7月在医院进行治疗60例中枢神经感染患者作为试验组,另选择同期在医院进行健康体检人员60名作为对照组;试验组患者及对照组检查者均接受CT及MRI检查,比较两组之间的临床诊断结果。结果试验组患者MRI及CT检查异常率均比对照组高;MRI检测试验组患者脑囊虫、化脓性脑膜炎、病毒性脑炎、结核性脑膜炎及新型隐球酵母菌脑膜炎异常率分别为100.0%、100.0%、87.5%、100.0%、100.0%,CT检测试验组患者脑囊虫、化脓性脑膜炎、病毒性脑炎、结核性脑膜炎及新型隐球酵母菌脑膜炎异常率分别为85.7%、75.0%、34.4%、76.9%、75.0%,MRI对各种脑膜炎异常检测率均高于CT检测。结论中枢神经系统感染性疾病进行诊断时,MRI的诊断率高于CT,MRI在临床上值得推广。OBJECTIVE With the continuous improvement of the medical level,the magnetic resonance imaging（MRI）is introduced following the CT and is characterized by rapid scanning and clear image,it becomes more and more popular in the clinical practice,especially in the related examinations of central nervous system.To provide reliable basis for diagnosis of the central nervous system infections and observe the effects of CT and MRI on diagnosis of the central nervous system infections.METHODS Totally 60 patients with central nervous system infections who were treated in the hospital from Jul 2013 to Jul 2014 were assigned as the experimental group,meanwhile,60 healthy people who underwent the physical examination were chosen as the control group,with totally120 cases enrolled.Both the experimental group and the control group received the CT and MRI,and the effects on clinical diagnosis were observed and compared between the two groups of patients.RESULTS The abnormal ratios of MRI and CT examinations of the experimental group were higher than those of the control group.When the MRI was used for detection of the patients of the experimental group,the patients with cerebral cysticercosis accounted for 100.0%,the patients with suppurative meningitis 100.0%,the patients with viral encephalitis87.5%,the patients with tubercular meningitis 100.0%,the patients with cryptococcal meningitis 100.0%.When the CT was used for detection of the patients of the experimental group,the patients with cerebral cysticercosis accounted for 85.7%,the patients with suppurative meningitis 75.0%,the patients with viral encephalitis34.4%,the patients with tubercular meningitis 76.9%,the patients with cryptococcal meningitis 75.0%;the detection rate of the MRI was higher than that of the CT in the diagnosis of the patients with cerebral cysticercosis,suppurative meningitis,viral encephalitis,tubercular meningitis,or cryptococcal meningitis in the experimental group.CONCLUSIONBoth MRI and CT have certain clinical effects on diagnosis of the centra
