MRI与CT在老年多发性脑梗死患者诊断中的临床结果对比分析

Comparison and analysis of the clinical results of MRI and CT in the diagnosis of elderly patients with multiple cerebral infarction

目的:探究并对比MRI、CT两种影像学技术在老年多发性脑梗死患者中的临床诊断价值。方法:收治老年多发性脑梗死患者40例,先后为这些患者进行CT检查与MRI检查,对比两种方法的诊断准确性与检测时间。结果:MRI的诊断准确率92.50%,高于CT的72.50%,差异有统计学意义(P<0.05)。此外,CT的检出时间(8.82±0.43)s,短于MRI的(899.48±101.16)s,差异均有统计学意义(P<0.05)。结论:在老年多发性脑梗死的诊断上,MRI具有更高的诊断准确性,CT具有更快的检出速度,临床可以将CT用于初诊,将MRI用于复诊。

Objective：To explore and compare the clinical diagnostic value of the two imaging techniques of MRI and CT in the elderly patients with multiple cerebral infarction.Methods：40 cases of elderly patients with multiple cerebral infarction were selected.CT examination and MRI examination were performed for these patients successively.The diagnostic accuracy and detection time of the two methods were compared.Results：The diagnostic accuracy of MRI was 92.50% higher than that of 72.50%of CT,and the differences was statistically significant（P〈0.05）.In addition,the detection time of CT（8.82±0.43）s was shorter than that of MRI（899.48±101.16）s,and the difference was statistically significant（P〈0.05）.Conclusion：In the diagnosis of multiple cerebral infarction in elderly patients,MRI has higher diagnostic accuracy,CT has faster detection speed,and CT can be used for initial diagnosis in clinic,and MRI can be used for referral.
