探讨CT与MRI对中枢神经系统感染的诊断对比

Comparison Study of CT and MRI in the Diagnosis of Central Nervous System Infection

目的研究分析电子计算机断层扫描(CT)与磁共振成像(MRI)在中枢神经系统感染(CNSI)诊断的效果和价值。方法选取2014年2月—2016年2月我院接收的148例中枢系统感染患者来探讨分析,作为观察组,并同期选取了148例健康体检者进行对比,作为对照组,对两组进行CT和MRI检查,对检测异常率进行对比分析。结果观察组有79例患者CT检测异常,异常率是53.38%,对照组有7例CT检测异常,异常率是4.73%,两组异常率对比差异存在统计学意义(χ~2=84.965,P=0.000);观察组有134例MRI检测异常,异常率90.54%,对照组有21例MRI检测异常,异常率14.19%,结果差异有统计学意义(χ~2=172.941,P=0.000)。结论 CT和MRI检查在中枢神经系统感染诊断中有较大的应用价值,MRI效果更好。

Objective To investigate the diagnostic value and the value of computed tomography （CT） and magnetic resonance imaging （MRI） in central nervous system infection （CNSI）. Methods 148 cases of patients with central nervous system infection to study from February 2014 to February 2016 were selected the patients as the observation group, 148 healthy volunteers were selected as control group, CT and MRI were examined in two groups of abnormal detection rate were analyzed. Results The observation group had 79 cases of patients with abnormal CT detection, the abnormal rate was 53.38%, the control group had 7 cases of CT detection of abnormal, the abnormal rate was 4.73%, the abnormal rate of two groups had statistical difference （χ2=84.965, P=0.000）; the observation group had 134 cases of MRI detection of abnormal, the abnormal rate was 90.54%, the control group had 21 cases of MRI detection of abnormal, the abnormal rate was 14.19%, there were signifcant differences （χ2=172.941, P=0.000）. Conclusion CT and MRI examination in the diagnosis of central nervous system infection has greater application value, effect of MRI is better and has more reference value.
