摘　　要：目的探讨磁共振成像(MRI)及磁敏感加权成像(SWI)诊断脑血管淀粉样脑出血的价值。方法回顾性分析我院2016年12月至2019年1月收治的150例临床诊断怀疑为脑血管淀粉样脑出血患者,所有患者均先后进行常规MRI以及SWI序列扫描,比较不同序列对脑血管淀粉样脑出血病灶的检出情况。结果 150例患者经病理组织学检查确诊为脑血管淀粉样脑出血的共有136例,其中SWI诊断阳性132例,阴性4例;常规MRI序列诊断阳性101例,阴性35例,SWI扫描阳性诊断率为97.06%,高于常规MRI扫描(74.26%),差异有统计学意义(P<0.05);SWI对于不同出血部位包括基底节出血、壳核出血、脑叶出血、丘脑出血检出率分别为97.92%、94.12%、100.00%、94.12%,高于常规MRI检出率(77.08%、70.59%、78.38%、64.71%),差异有统计学意义(P<0.05)。结论脑血管淀粉样脑出血影像学诊断过程中,SWI相对于常规MRI可提供更详细、准确的诊断信息,诊断价值大于常规MRI。Objective To explore the diagnostic value of magnetic resonance imaging(MRI)and susceptibilityweighted imaging(SWI)fo r cerebral a myloid hemorrhage of ce re b ral vascular.Methods A retrospective analysis was performed on 150 patients clinically suspected with amyloid cerebral hemorrhage of cerebral vascular who were admitted to the hospital from December 2016 to January 2019.All patients underwent routine MRI,and SWI sequence scans in turn.The detection conditions of different sequences for ce rebral amyloid hemorrhage of cerebral vascular were compared.Results Of the 150 patients,there were136 cases confirmed with cerebral amyloid hemorrhage of cerebral vascular by histo pat ho logical examination.SWI diagnosis showed that there were 132 positive cases and 4 negative cases.Routine MRI sequence diagnosis showed that there were 101 positive cases and35 negative cases.The positive diagnosis rate of the SWI scan was higher than that of a routine MRI scan(97.06%vs.74.26%)(P<0.05).The detection rates of SWI for different hemorrhage sites such as basal ganglia hemorrhage,shell nucleus hemorrhage,ce re b ral hemorrhage,and thalamic hemorrhage were 97.92%.94.12%,100.00%and 94.12%,were higher than those of routine MRI(77.08%,70.59%,78.38%,64.71%)(P<0.05).Conclusion In the imaging diagnosis process for cerebral vascular amyloid cerebral hemorrhage,SWI can provide more detailed and accurate diagnostic information than routine MRI.Moreover,the diagnostic value is greater than that of a routine MRI sequence.
