摘　　要：目的:探讨老年多发性脑梗死病例行以MRI、CT检查的准确性。方法:择取2020年1月至2021年1月我院收诊86例老年多发性脑梗死病例,随机行以分组,比较行MRI检查的43例病例(MRI组)和行CT检查的43例病例(CT组)多发性脑梗死检出率、准确率,并记录检出病灶数、大小以及不同发病时间梗死病灶检出情况。结果:MRI组相较于CT组呈现出更高的检出率、准确率(88.37%vs69.77%、86.05%vs67.44%),差异显著(P<0.05)。MRI组病灶检出数量为(2.65±0.59)个,高于对照组,病灶大小(8.65±1.67)mm^(2)、检查用时(10.48±2.14)min,均较对照组低,差异显著(P<0.05)。不同发病时间检出率比较,<24h的检出率MRI组(91.67%)高于CT组(33.33%),差异显著(P<0.05),其他时间区间两组差异无意义(P>0.05)。结论:MRI于老年多发性脑梗死的临床诊断中应用,拥有相较于CT更高的检出率和准确性,可为首选方法于临床推广。Objective:To investigate the accuracy of MRI and CT examinations in elderly patients with multiple cerebral infarction.Methods:A total of 86 elderly patients with multiple cerebral infarction admitted to our hospital from January 2020 to January 2021 were selected and randomly divided into groups.The 43 cases who underwent MRI examination(MRI group)and the 43 cases who underwent CT examination were compared.The detection rate and accuracy of multiple cerebral infarction in cases(CT group)were recorded,and the number and size of detected lesions and the detection of infarct lesions at different onset times were recorded.Results:Compared with the CT group,the MRI group showed higher detection rate and accuracy(88.37%vs 69.77%,86.05%vs 67.44%),and the difference was significant(P<0.05).The number of detected lesions in the MRI group was(2.65±0.59),which was higher than that in the control group.The size of the lesions(8.65±1.67)mm’and the examination time(10.48±2.14)min were lower than those in the control group,and the difference was significant(P<0.05)..Comparing the detection rates of different onset times,the detection rate of<24h in the MRI group(91.67%)was higher than that in the CT group(33.33%),the dfference was significant(P<0.05),and there was no significant dfference between the two groups in other time intervals(P>0.05).Conclusion:The application of MRI in the clinical diagnosis of multiple cerebral infarction in the elderly has higher detection rate and accuracy than CT,and can be the preferred method for clinical promotion.
