目的:探讨CT、磁共振诊断中枢神经系统感染的临床价值。方法:35例中枢神经感染患者作为观察组,另选20例健康体检者作为对照组。两组受检者均行CT、MRI诊断,对两种诊断方法的阳性率进行比较。结果:观察组CT诊断阳性率为57.1%(20/35);MRI诊断阳性率为97.1%(34/35),MRI诊断阳性率明显高于CT诊断。且观察组的诊断阳性率明显高于对照组受检者的诊断阳性率。结论:MRI对于中枢神经系统感染诊断临床价值高于CT诊断法,MRI或将两种诊断法相结合可进一步提高诊断准确率。
Objective: To investigate the clinical value of CT and magnetic resonance imaging in the diagnosis of central nervous system infection. Methods: 35 patients with central nervous system infection were selected as observation group and 20 healthy subjects were selected as control group. Two groups of subjects underwent CT, MRI diagnosis, the positive rate of the two diagnostic methods were compared. Results: The positive rate of CT diagnosis in observation group was 57.1% (20/35). The positive rate of MRI diagnosis was 97.1% (34/35). The positive rate of MRI diagnosis was significantly higher than that of CT. The positive rate of diagnosis in the observation group was significantly higher than that in the control group. Conclusion: The clinical value of MRI in the diagnosis of central nervous system infection is higher than that of CT, MRI or the combination of two diagnostic methods to further improve the diagnostic accuracy.
