摘要
目的对比在急性缺血性脑卒中的临床诊断中应用计算机断层扫描(computed tomography,CT)和核磁共振成像(magnetic resonance imaging,MRI)检查的效果与检出率。方法选取2022年12月—2023年12月临沂河东医院收治的90例疑似急性缺血性脑卒中患者为研究对象,以病理结果作为金标准,分别实行CT平扫和MRI检查,比较两种检查方式在急性缺血性脑卒中的检出情况和诊断效能。结果病理结果显示,90例疑似急性缺血性脑卒中患者中共检出阳性41例、阴性49例,检出率为45.56%。CT平扫共检出阳性29例、阴性61例,检出率为32.22%。MRI检查共检出阳性40例、阴性50例,检出率为44.44%。CT平扫和MRI检查的在急性缺血性脑卒中的特异度(89.80%vs 97.96%)比较,差异无统计学意义(χ^(2)=2.840,P>0.05)。MRI检查的灵敏度(95.12%)、准确度(96.67%)、阳性预测值(97.50%)、阴性预测值(96.00%)均高于CT平扫(58.54%、75.56%、82.76%、72.13%),差异有统计学意义(χ^(2)=15.413、16.769、4.601、11.034,P均<0.05)。结论与CT平扫相比,MRI检查具有更高的诊断效能,应用于急性缺血性脑卒中的诊断结果更佳。
Objective Compared the effectiveness and detection rate of computed tomography(CT)and magnetic resonance imaging(MRI)in the clinical diagnosis and the detection rate of acute ischemic stroke.Methods From December 2022 to December 2023,90 suspected patients with acute ischemic stroke were selected in our hospital,and pathological results were used as the gold standard for CT plain scan and MRI examination,respectively.Compared the effectiveness and detection of CT plain scan and MRI in acute ischemic stroke.Result The pathological results of 90 suspected acute ischemic stroke patients showed that a total of 41 cases were positive and 49 cases were negative,with a detection rate of 45.56%.A total of 29 cases were positive and 61 cases were negative in CT plain scan,with a detection rate of 32.22%.A total of 40 cases were positive and 50 cases were negative in MRI examination,with a detection rate of 44.44%.The specificity of CT plain scan and MRI examination in acute ischemic stroke was similar(89.80%vs 97.96%),and the differences were not statistically significant(both P>0.05).The sensitivity(95.12%),accuracy(96.67%),positive predictive value(97.50%),and negative predictive value(96.00%)of MRI examination were all higher than those of CT plain scan(58.54%,75.56%,82.76%,72.13%),and the differences were statistically significant(all P<0.05).Conclusion The use of MRI in the clinical diagnosis of acute ischemic stroke is more effective and has a higher detection rate,which can provide reference information for clinical practice and has high application value.
