摘　　要：目的探讨中枢神经系统感染患者MRI及CT的临床诊断价值分析。方法选择2015年5月-2017年5月于医院接受治疗的70例中枢神经系统感染患者为治疗组,选择同期于医院行体检的健康人员70名为对照组。两组研究对象均采用MRI及CT检查,比较两组研究对象的诊断效果及治疗组患者两种方式检测异常率等情况。结果中枢神经系统感染患者中以病毒性脑炎35例占50.00%为主,其次为结核性脑膜炎15例占21.43%;治疗组CT检查异常率为55.71%,高于对照组的7.14%,治疗组MRI检查异常率为92.86%,高于对照组的15.71%(P<0.05);治疗组MRI检查异常率高于CT检查方式(P<0.05);两种检查方法对病毒性脑炎、结核性脑膜炎检出异常率比较差异有统计学意义(P<0.05);两组检查方法病因的检出率比较差异有统计学意义(P<0.05)。结论 MRI及CT检查方式均能有效地检查中枢神经系统感染患者,而MRI检查方法诊断率高于CT检测,选择MRI与CT联合诊断方式,能够取得明显的诊断效果,并对患者的病情以及预后分析提供依据。OBJECTIVE To investigate the clinical diagnostic value of MRI and CT in patients with central nervous system infections.METHODS A total of 70 patients with central nervous system infections treated in our hospital from May 2015 to May 2017 were selected as treatment group.At the same time,70 healthy people were selected as control group.The two groups of patients were examined by MRI and CT.The diagnostic effects of the two groups were compared,and the abnormal rate was detected by two methods in the treatment group.RESULTS Among the patients with central nervous system infection,35 cases were viral encephalitis accounting for 50%,followed by 15 cases of tuberculous meningitis,accounting for 21.43%.The abnormal rate of CT in treatment group was 55.71%,which was higher than 7.14%in control group.The abnormal rate of MRI examination in treatment group was 92.86%,which was significantly higher than 15.71%in control group（P〈0.05）.The abnormal rate of MRI examination in treatment group was higher than that of CT,and the difference between the two methods was significant（P〈0.05）.There was significant difference in the abnormal rate of detection of viral encephalitis and tuberculous meningitis by the two methods（P〈0.05）.Etiology detection rate between the two groups was significant（P〈0.05）.CONCLUSION MRI and CT were able to detect the patients with central nervous system infection effectively,and the diagnostic rate of MRI was higher than that of CT.The combined diagnosis of MRI and CT can obtain obvious effect,and has a certain reliable basis for the patient＇s condition and prognosis analysis.
