MSCT和MRI在脑血管疾病中的诊断价值比较

Comparison of Diagnostic Value of MSCT and MRI in Cerebrovascular Diseases

目的比较多层螺旋CT(MSCT)与核磁共振(M R I)在脑血管疾病中的诊断价值。方法回顾性分析医院2015.06~2018.06间收治的101接受过MSCT与MRI检查的脑血管疾病住院患者临床资料,比较MSCT与MRI在诊断脑血管疾病中的应用价值。结果以出院诊断提示,101例患者中脑出血21例、脑梗死42例,动脉瘤11例,其余27例未出现异常状况,以出院诊断结果为“金标准”,MSCT脑出血、脑梗死及动脉瘤阳性检出率分别为85.71%、83.33%及63.64%,MRI阳性检出率分别为90.48%、95.24%、100.00%,MSCT+MRI阳性检出率分别为100.00%、97.62%及100.00%,MSCT在诊断脑血管疾病中的灵敏度、特异度及准确度分别为81.08%、74.07%、79.21%,MRI分别为94.59%、88.89%、93.07%,MSCT+MRI分别为98.65%、92.59%、97.03%。结论MSCT与MRI在脑血管疾病中均具有良好的诊断价值,MRI对颅内微小病灶阳性检出效果优于MSCT,但MRI同样具有检查费用高昂的缺点,建议临床根据患者具体病情与需求选择合适的检查方式。

Objective To compare the diagnostic value of multi-slice spiral CT(MSCT)and magnetic resonance imaging(MRI)in cerebrovascular diseases.Methods The clinical data of 101 inpatients with cerebrovascular diseases who underwent MSCT and MRI in the hospital from June 2015 to June 2018 were analyzed retrospectively.The application value of MSCT and MRI in the diagnosis of cerebrovascular diseases was compared.Results According to the diagnosis suggestion of discharge,there were 21 cases of cerebral hemorrhage,42 cases of cerebral infarction,11 cases of aneurysm and 27 cases without abnormal condition among 101 patients.The diagnosis results of discharge were taken as gold standards,and the positive detection rates of cerebral hemorrhage,cerebral infarction and aneurysms by MSCT were 85.71%,83.33% and 63.64% respectively,and the positive detection rates by MRI were 90.48%,95.24% and 100.00%respectively,and the positive detection rates by MSCT+MRI were 100.00%,97.62% and 100.00%respectively.The sensitivity,specificity and accuracy in the diagnosis of cerebrovascular diseases were 81.08%,74.07% and 79.21%by MSCT,and were 94.59%,88.89% and 93.07%respectively by MRI,and were 98.65%,92.59%and 97.03% respectively by MSCT+MRI.Conclusion Both MSCT and MRI have good diagnostic value in cerebrovascular diseases.MRI is superior to MSCT in detecting small positive intracranial lesions.However,MRI also has the disadvantage of high cost of examination.It is recommended to select appropriate examination methods in clinical application according to the specific conditions and needs of patients.
