MRI和CT在急性脑梗死诊断中的应用价值研讨

The application value of MRI and CT in the diagnosis of acute cerebral infarction

目的:评定急性脑梗死诊断中采用磁共振成像(MRI)和计算机断层成像(CT)诊断的效果。方法:选取昌邑市人民医院2020年3月—2023年3月期间接诊的110例疑似急性脑梗死患者,均实施MRI和CT诊断,以数字减影血管造影(DSA)为金标准,分析不同诊断方式应用在急性脑梗死诊断中的价值。结果:MRI的诊断灵敏度、准确率明显高于CT诊断(P<0.05);两者诊断特异度比较差异无统计学意义(P>0.05);MRI在不同病灶(额叶、颞叶、基底节、脑干、小脑、枕叶)的检出准确率均高于CT诊断,其中基底节、脑干差异有统计学意义(P<0.50)。结论:相比于CT诊断,急性脑梗死诊断中MRI的应用效能更高,在不同病灶的检出率更高,且MRI的诊断灵敏度与准确率更高,值得临床推广价值。

Objective To evaluate the effect of MRI and CT in the diagnosis of acute cerebral infarction.Methods A total of 110 suspected patients with acute cerebral infarction were selected from Changyi People's Hospital from March 2020 to March 2023 for diagnosis by MRI and CT.Digital subtraction angiography(DSA)was used as the gold standard to analyze the diagnostic value of different diagnostic methods in the diagnosis of acute cerebral infarction.Results The sensitivity and accuracy of MRI were significantly higher than that of CT diagnosis(P<0.05).There was no significant difference in diagnostic specificity between MRI and CT(P>0.05).The detection accuracy of MRI in different lesions(frontal lobe,temporal lobe,basal ganglia,brain stem,cerebellum,occipital lobe)was higher than that of CT diagnosis,and the differences in basal ganglia and brain stem were statistically significant(P<0.50).Conclusion Compared with CT diagnosis,magnetic resonance imaging in the diagnosis of acute cerebral infarction has higher application efficiency,higher detection rate in different lesions,and higher sensitivity and accuracy,which is worthy of clinical promotion.
