MRI与CT影像检查在多发性脑梗死诊断中的应用分析

Application of MRI and CT imaging in the diagnosis of multiple cerebral infarction

目的:探讨多发性脑梗死采用颅脑磁共振成像(MRI)诊断的价值。方法:选取2022年2月—2023年2月滨州市中心医院收治的120例多发性脑梗死患者的为研究对象,全部患者均经手术病理确诊,对120例患者分别采取MRI检查与CT检查,对比MRI与CT的诊断效能。结果:与CT检查相比,MRI检查对不同直径梗死病灶的检出率更高,差异有统计学意义(P<0.05);MRI检查对<24 h、24~72 h发病时间的梗死病灶的检出率更高,差异有统计学意义(P<0.05),而对>72 h病灶的检出率比较差异无统计学意义(P>0.05);MRI检查对基底节区、脑干、脑旁室、顶叶以及丘脑部位的梗死病灶检出率更高,差异有统计学意义(P<0.05)。结论:临床上采用MRI、CT检查均能有效检出多发性脑梗死,但MRI检查在多发性脑梗死的早期病灶、不同直径病灶以及不同部位病灶的诊断价值更高。

Objective To investigate the diagnostic value of cranial magnetic resonance images(MRI)in multiple cerebral infarction.Methods A total of 120 patients with multiple cerebral infarction admitted to Binzhou Central Hospital from February 2022 to February 2023 were selected,all the patients were diagnosed by surgical pathological diagnosis.MRI and CT were taken in 120 patients respectively,and the diagnostic efficacy of MRI and CT was compared.Results Compared with the detection rate of different diameter infarct lesions by MRI was higher,the difference was statistically significant(P<0.05).The detection rate of infarction lesions with onset time of<24 h and 24-72 h was higher,the difference was statistically significant(P<0.05),but there was no difference in the detection rate of infarction lesions with onset time of>72 h(P>0.05).MRI had a higher detection rate in basal ganglia,brainstem,paraventricular ventricle,parietal lobe and thalamus,the difference was statistically significant(P<0.05).Conclusion MRI and CT can effectively detect multiple cerebral infarction,but MRI has higher diagnostic value in early stage,different diameter and different position.
