摘　　要：目的分析磁共振磁敏感加权成像(SWI)用于脑血管病微出血灶诊断的临床价值。方法选取2020年4月至2022年4月我院收治的82例脑血管病伴微出血患者,均给予常规MRI序列、弥散加权成像(DWI)序列及SWI序列扫描,比较不同检查方式的脑微出血灶检出率,观察脑微出血灶在各序列的影像学表现,统计不同部位微出血灶检出情况。结果SWI序列的脑微出血灶检出率为100.00%,明显高于常规MRI序列的59.76%及DWI序列的68.29%(P<0.05)。82例患者共有517个微出血灶,SWI序列各部位病灶检出数高于MRI常规序列、DWI序列(P<0.05)。结论SWI诊断脑血管病微出血灶具有极高检出率,检出效果优于常规MRI及DWI,在脑血管病患者的诊断中可优先选取。Objective To analyze the clinical value of magnetic resonance susceptibility-weighted imaging(SWI)in the diagnosis of microbleeds of cerebrovascular disease.Methods 82 patients with cerebrovascular disease and microbleeds admitted to our hospital from April 2020 to April 2022 were selected and scanned with conventional MRI sequence,diffusion-weighted imaging(DWI)sequence and SWI sequence.The detection rate of cerebral microbleeds by different examination methods was compared,the imaging performance of cerebral microbleeds in each sequence was observed,and the detection of microbleeds in different parts was calculated.Results The detection rate of cerebral microbleeds of SWI sequence was 100.00%,significantly higher than 59.76%of conventional MRI sequence and 68.29%of DWI sequence(P<0.05).A total of 517 microbleeds were checked out in 82 patients,and the number of lesions detected in various parts of SWI sequence was higher than that in the conventional MRI sequence and DWI sequence(P<0.05).Conclusions SWI in the diagnosis of microbleeds of cerebrovascular disease has a very high detection rate,and better detection effect than conventional MRI and DWI,which can be prioritized in the diagnosis of patients with cerebrovascular disease.
