MRI-SWI诊断脑出血性病变的价值分析

Analysis on the Value of MRI-SWI in the Diagnosis of Cerebral Hemorrhagic Lesions

目的探讨MRI-磁敏感成像(SWI)诊断脑出血性病变的价值。方法选取2021年2月至2024年2月我院收治的90例脑出血性病变患者,均接受常规MRI及SWI扫描。比较两种方式对脑出血病灶、病因检出情况,并分析SWI评估脑出血预后的价值。结果MRI-SWI扫描对出血灶及微出血灶的检出率高于常规MRI,检测出血面积及出血量均高于常规MRI(P<0.05)。MRI-SWI对脑出血特殊病因检出率高于常规MRI(P<0.05)。相关性分析显示,MRI-SWI的出血面积及出血量与GCS及GOS评分均呈负相关(P<0.05)。结论MRI-SWI诊断脑出血病变可检出微出血病灶,精确地测量出血面积及出血量,对脑出血病因的确定价值较高,可用于评估患者预后。

Objective To explore the value of MRI-susceptibility weighted imaging(SWI)in the diagnosis of cerebral hemorrhagic lesions.Methods 90 patients with cerebral hemorrhagic lesions admitted to our hospital from February 2021 to February 2024 were selected,and given routine MRI and SWI scanning.The detection of cerebral hemorrhagic lesions and etiology were compared between two methods,and the value of SwI in the evaluation of cerebral hemorrhage prognosis was analyzed.Results The detection rates of bleeding and microbleeding of MRI-SWI were higher than those of routine MRI,and the bleeding area and blood loss were higher than those of routine MRI(P<0.05).The detection rate of special causes of cerebral hemorrhage by MRI-SWI was higher than that by routine MRI(P<0.05).Correlation analysis showed that MRI-SWI bleeding area and blood loss were negatively correlated with GCS and GOS scores(P<0.05).Conclusions MRI-SWI can detect the microbleeding lesions,and accurately measure the bleeding area and blood loss,which has higher value in determining the cause of cerebral hemorrhage,and can be used to evaluate the prognosis of patients.
