摘要
目的:探讨CT联合MRI检查对脑梗死合并脑出血的诊断效果.方法:选取 2021 年 6 月—2023 年 5 月连云港市第一人民医院收治的 86 例疑似脑梗死合并脑出血患者作为研究对象.以临床观察和综合检查结果为"金标准".所有患者均进行常规MRI及CT检查.记录CT、MRI及两者联合的诊断结果,并通过敏感度、特异度、阳性预测值、阴性预测值、准确度和Kappa值评估MRI、CT及两者联合的诊断效能.结果:金标准确诊脑梗死合并脑出血 71 例,单纯脑出血 7 例,单纯脑梗死 8 例.CT检查确诊脑梗死合并脑出血 52 例,单纯脑梗死或脑出血 7 例,敏感度、特异度、准确度分别为 73.24%、46.67%、68.60%.MRI检查确诊脑梗死合并脑出血 55 例,单纯脑梗死或脑出血 9 例,敏感度、特异度、准确度分别为 77.46%、60.00%、74.42%.CT联合MRI确诊脑梗死合并脑出血 59 例,单纯脑梗死或脑出血 13 例,敏感度、特异度、准确度分别为 83.10%、86.67%、83.72%.CT联合MRI检查的特异度、准确度均高于CT检查(P＜0.05).结论:CT联合MRI对脑梗死合并脑出血的诊断效能较高.
Abstract
Objective:To explore the diagnostic effect of CT combined with MRI on cerebral infarction complicated with cerebral hemorrhage.Method:A total of 86 patients with suspected cerebral infarction complicated with cerebral hemorrhage admitted to the First People's Hospital of Lianyungang from June 2021 to May 2023 were selected as the study objects.Clinical observation and comprehensive examination results was the"gold standard".All patients underwent routine MRI and CT examination.The diagnostic results of CT,MRI and their combination were recorded,and the diagnostic efficacy of MRI,CT and their combination was evaluated by sensitivity,specificity,positive predictive value,negative predictive value,accuracy and Kappa value.Result:The gold standard confirmed 71 cases of cerebral infarction complicated with cerebral hemorrhage,7 cases of simple cerebral hemorrhage,8 cases of simple cerebral infarction.CT examination confirmed 52 cases of cerebral infarction complicated with cerebral hemorrhage,7 cases of simple cerebral infarction or cerebral hemorrhage,and the sensitivity,specificity and accuracy respectively was 73.24%,46.67%and 68.60%.MRI examination confirmed 55 cases of cerebral infarction complicated with cerebral hemorrhage and 9 cases of simple cerebral infarction or cerebral hemorrhage,and the sensitivity,specificity and accuracy respectively was 77.46%,60.00%and 74.42%.CT combined with MRI confirmed 59 cases of cerebral infarction complicated with cerebral hemorrhage,13 cases of simple cerebral infarction or cerebral hemorrhage,and the sensitivity,specificity and accuracy respectively was 83.10%,86.67%and 83.72%.The specificity and accuracy of CT combined with MRI were higher than those of CT(P＜0.05).Conclusion:The diagnostic efficiency of CT combined with MRI is is high in cerebral infarction complicated with cerebral hemorrhage.
