MRI与CT在老年多发性脑梗死诊断中的对比分析

Clinical comparison of MRI and CT in the diagnosis of the patients with multiple cerebral infarction in the elderly

目的:对比MRI与CT检查在老年多发性脑梗死诊断中的应用效果。方法:对98例多发性脑梗死患者分别应用MRI及CT检查,观察并对比两种方法对脑梗死的总检出率,不同时间梗死的检出率,以及不同部位梗死异常的检出情况。结果:MRI的总检出率为92.56%,明显高于CT的54.08%(P<0.01)。梗死24小时以内、梗死24~72小时的总检出率,MRI明显高于CT(P<0.01)。MRI对脑干及小脑梗死的检出率明显高于CT检查(P<0.05)。结论:针对老年多发性脑梗死患者,MRI的诊断效果明显优于CT检测。

Objective:To explore the application effect of MRI and CT in the diagnosis of the patients with multiple cerebral infarction in the elderly.Methods:98 cases with multiple cerebral infarction were examined by MRI and CT respectively.We observed and compared the total detection rate of cerebral infarction,the detection rate of different time infarction and the abnormal situation in different parts of infarction.Results:The total detection rate of MRI was 92.56%,and it was significantly higher than that of CT of 54.08%(P<0.01).For the total detection rate of infarction within 24 hours and infarction from 24 to 72 hours,MRI was significantly higher than that in CT(P<0.01).For the detection rate of brainstem and cerebellar infarction,MRI was significantly higher than that in CT(P<0.05).Conclusion:For the multiple cerebral infarction in elderly patients,the clinical diagnosis of MRI is better than CT.
