摘要
目的探讨磁共振成像(MRI)和电子计算机断层扫描(CT)在急性脑梗死(ACI)诊断中的应用价值。方法选取本院2018年10月—2020年12月收治的104例ACI患者作为研究对象,均接受MRI和CT检查,评估MRI和CT诊断ACI的价值。结果发病至入院时间<6 h、6 h~24 h、24 h~72 h的患者MRI检出率高于CT(P<0.05),发病至入院时间>72 h的患者,MRI检出率和CT比较差异无统计学意义(P>0.05);发病至入院时间<6 h、6 h~24 h、>72 h的患者梗死病灶表观弥散系数(ADC)值均低于对侧脑组织(P<0.05)。结论MRI在ACI早期诊断中具有较好的诊断价值,ADC值可为判断脑梗死病灶部位提供客观依据。
Objective To discuss the application value of magnetic resonance imaging(MRI)and computer tomography(CT)in the diagnosis of acute cerebral infarction(ACI).Methods A total of 104 ACI patients admitted to our hospital from October2018 to December 2020 were selected as the research objects.All of them underwent MRI and CT examinations,and the value of MRI and CT in the diagnosis of ACI was evaluated.Results The MRI detection rate of patients whose time from onset to admission is less than 6 h,6 h-24 h,or 24 h-72 h is higher than the CT detection rate(P<0.05).For patients whose time from onset to admission was>72 h,there was no statistical significance on the difference between MRI detection rate and the CT detection rate(P>0.05);the apparent diffusion coefficient(ADC)values of infarct lesions in patients whose time from onset to admission were<6 h,6 h-24 h,and>72 h were lower than those of the contralateral brain tissue(P<0.05).Conclusion MRI has a good diagnostic value in the early diagnosis of ACI,and the ADC value can provide an objective basis for judging the location of cerebral infarction.
