腔隙性脑梗死应用CT与核磁共振检查的诊断对比

Comparison of CT and MRI in Diagnosis of Lacunar Cerebral Infarction

目的:评价CT以及核磁共振(MRI)对于腔隙性脑梗死(LI)的诊断作用。方法:选择2020年1月~2023年8月入院诊断的93例LI患者。均行CT诊断以及MRI诊断,对比诊断效果。结果:MRI组的阳性检出率高于CT组,MRI组对于各病灶位置的检出率均高于CT组,对比数据有差异(P<0.05)。MRI组对于发病<24h的病灶检出率高于CT组,对比数据有差异(P<0.05)。以手术病理为金标准,MRI组的诊断准确率、敏感度、阳性预测值均高于CT组,对比数据有差异(P<0.05)。MRI组所检出的梗死直径大于CT组,病灶数量多于CT组,检出时间长于CT组,检查费用多于CT组,对比数据有差异(P<0.05)。结论:MRI对于LI的检出率更高,能够判断病灶位置,于发病早期明确诊断该病,具有较高的诊断效能。但其检出时间较长,检查费用较高,因此具有局限性。在临床诊断中,可根据患者的实际情况合理选择诊断方法,进而提高疾病诊断效率。

Objective:To evaluate the diagnostic value of CT and MRI in lacunar cerebral infarction(LI).Methods:93 patients with LI who were admitted to hospital between January 2020 and August 2023 were selected.CT diagnosis and MRI diagnosis were performed to compare the diagnostic effect.Results:The positive detection rate of MRI group was higher than that of CT group,and the detection rate of all lesion locations in MRI group was higher than that in CT group,and the comparative data were different(P<0.05).The detection rate of lesions<24h in MRI group was higher than that in CT group(P<0.05).Taking surgical pathology as the gold standard,the diagnostic accuracy,sensitivity and positive predictive value of MRI group were higher than those of CT group(P<0.05).The diameter of infarcts detected in MRI group was larger than that in CT group,the number of lesions was larger than that in CT group,the detection time was longer than that in CT group,and the examination cost was larger than that in CT group,with differences(P<0.05).Conclusion:MRI has a higher detection rate of LI,can determine the location of the lesion,and clearly diagnose the disease in the early stage,and has a high diagnostic efficiency.However,its detection time is long and the inspection cost is high,so it has limitations.In clinical diagnosis,diagnosis methods can be reasonably selected according to the actual situation of patients,so as to improve the efficiency of disease diagnosis.
