摘　　要：目的探讨MRI与CT在老年多发性脑梗死诊断中的应用价值。方法选取2017年4月至2019年4月在我院治疗的老年多发性脑梗死患者150例,均给予CT和MRI检查,比较两种方法病灶检出情况。结果 MRI检出率为96.00%,明显高于CT检查(59.33%,P<0.05);在梗死时间<24h、24h~72h患者中,MRI检出率分别为93.75%和96.10%,明显高于CT检查(40.63%、50.65%,P<0.05);在梗死时间>72h患者中,MRI和CT检出率比较差异无统计学意义(P>0.05);MRI检查平均病灶检出数、检查时间分别为(2.40±0.60)个和(19.20±3.22)min,明显高于CT检查(P<0.05),而平均病灶检出大小为(8.44±1.03)mm^(2),明显低于CT检查(P<0.05);MRI检查额叶、基底节区、丘脑异常检出率分别为65.33%、78.6 7%和44.00%,明显高于CT检查(P<0.05)。结论相较于CT检查,MRI检查在老年多发性脑梗死中有较好的应用价值,值得临床使用。Objective To explore the value of MRI and CT in the diagnosis of senile multiple cerebral infarction.Methods 150 elderly patients with multiple cerebral infarction treated in our hospital from April 2017 to April 2019 were selected,all patients were examined by CT and MRI,the detection of lesions by two methods were compared.Results The detection rate of MRI was 96.00%,which was significantly higher than that of CT 59.33%(P<0.05);In patients with infarction time<24 hours,24 hours to 72 hours,the detection rates of MRI were 93.75%and 96.10%,which were significantly higher than those of CT examination in 40.63%and 50.65%(P<0.05);In patients with infarction time>72 hours,there was no significant difference in the detection rate of MRI and CT(P>0.05);The average detection number and time of MRI examination were(2.40±0.60)and(19.20±3.22)minutes,which were significantly higher than those of CT examination(P<0.05),while the average detection size of lesions was(8.44±1.03)mm^(2),which was significantly lower than that of CT examination(P<0.05);The detection rates of abnormal frontal lobe,basal ganglia and thalamus by MRI were 65.33%,78.67%and 44.00%,which were significantly higher than those by CT(P<0.05).Conclusion Compare with CT examination,MRI examination has better application value in senile multiple cerebral infarction and is worth clinical use.
