目的对比MRI(核磁共振)与CT(多层面螺旋CT)应用于老年多发性脑梗死诊断的效果。方法随机抽取我院老年多发性脑梗死临床诊断患者90例,均行MRI与CT检查,比较总检出率、梗死发生于不同部位的检出情况及不同梗死时间(24h以内、24~72h)检出率。结果 MRI组患者脑梗死总检出率以及不同梗死时间的检出率均高于CT组,P<0.05;CT组在脑室旁、丘脑、基底节区、额叶、顶叶、颞叶及小脑处的脑梗死异常检出数均少于MRI组,且MRI的异常检出率在除丘脑及脑室旁的各部位均有高于35%的提高。结论 MRI诊断老年多发性脑梗死检出率高于CT检查,且MRI对于不同部位发生梗死的检出率也高于CT。
Objective To compare the effect of MRI (magnetic resonance imaging) and CT (multi-slice spiral CT) in the diagnosis of senile multiple cerebral infarction. Methods Totally 90 cases of elderly patients with multiple cerebral infarction were randomly selected. MRI and CT were performed to compare the detection rate, the detection of infarction in different sites and the different infarct time (within 24h, 24 ~ 72h) The detection rate. Results The detection rate of cerebral infarction and the detection rate of different infarct time in MRI group were higher than those in CT group (P <0.05). In CT group, the detection rate of cerebral infarction in cerebral ventricle, thalamus, basal ganglia, frontal lobe, parietal lobe, temporal lobe and cerebellum The number of detected abnormalities of cerebral infarction was less than that of MRI group, and the abnormal detection rate of MRI was higher than 35% in all parts except thalamus and periventricular. Conclusion The detection rate of MRI diagnosis of senile multiple cerebral infarction is higher than that of CT examination, and MRI detection rate of infarction in different parts is also higher than that of CT.
