摘　　要：目的:分析计算机断层扫描(CT)、磁共振成像(MRI)联合检查在多发性急性脑梗死(ACI)诊断中的效能。方法:选取2021年8月至2023年8月该院收治的85例疑似ACI患者进行前瞻性研究,所有患者均行CT、MRI检查,并以数字减影血管造影(DSA)为金标准,比较CT、MRI单项及联合检查诊断ACI的结果、效能,并采用Kappa检验分析CT、MRI单项及联合检查与DSA检查的一致性。结果:金标准检查结果显示,85例疑似ACI患者中,阳性60例,阴性25例;CT检查结果显示,阳性55例,阴性30例;MRI检查结果显示,阳性56例,阴性29例;CT、MRI联合检查结果显示,阳性59例,阴性26例;CT、MRI联合检查诊断ACI的灵敏度、准确度均高于CT、MRI单项检查,差异有统计学意义(P<0.05);Kappa检验结果显示,CT检查与金标准检查诊断ACI的一致性尚可;MRI检查诊断与金标准检查诊断ACI的一致性尚可;联合检查诊断与金标准检查诊断ACI的一致性良好。结论:CT、MRI联合检查诊断ACI的效能高于二者单项检查。Objective:To analyze efficiency of combined examination of computed tomography(CT)and magnetic resonance imaging(MRI)in diagnosis of multiple acute cerebral infarction(ACI).Methods:A prospective study was conducted on 85 patients with suspected ACI admitted to the hospital from August 2021 to August 2023.All patients underwent CT and MRI examinations.Using the results of digital subtraction angiography(DSA)as the gold standard,the results and efficiency of single and combined examination of CT and MRI in the diagnosis of ACI were compared.Kappa test was used to analyze the consistencies of CT,MRI single and combined examination with DSA examination.Results:The gold standard showed 85 patients with suspected ACI,among them,60 cases were positive and 25 cases were negative.CT examination showed that 55 cases were positive and 30 cases were negative.MRI examination results showed that 56 cases were positive and 29 cases were negative.The combined CT and MRI showed that 59 cases were positive and 26 cases were negative.The sensitivity and the accuracy of combined examination of CT and MRI in the diagnosis of ACI were higher than those of single examination of,and the differences were statistically significant(P<0.05).Kappa test results showed that the consistency between CT examination and gold standard examination in the diagnosis of ACI was acceptable;the consistency between MRI diagnosis and gold standard examination in the diagnosis of ACI was acceptable;and the consistency between combined examination and gold standard examination in the diagnosis of ACI was good.Conclusions:The efficiency of combined CT and MRI in the diagnosis of ACI is higher than that of single examination.
