磁敏感成像在脑梗死中的应用价值

目的：探讨磁敏感成像（SWI）在脑梗死患者中对脑微出血的诊断价值,以及对脑梗死可能出现的脑出血等潜在危险性的预见。方法：42例腔隙性脑梗死患者,其中18例合并高血压病,4例合并2型糖尿病,12例合并有高血压病及2型糖尿病,应用1.5TMR行常规MRI和SWI序列成像检查,并结合临床资料进行分析。结果：23例脑梗死患者脑内有微出血灶,在SWI上呈点状、圆形、椭圆形低信号。总数达266个,直径为1.8-7.4mm。分布于皮层、皮层下,基底节区、丘脑,脑干和小脑。结论：SWI在检出脑微出血灶方面有明显的优势。对于存在脑梗死的患者SWI序列可敏感的显示脑内微出血灶,可为临床治疗脑梗死提供参考。

The Diagnosis Value of SWI in Cerebral Infarction

Objective： To investigate SWI in patients with cerebral infarction in the diagnosis of cerebral microbleeds value and clinical application of SWI therapy of cerebral hemorrhage cerebral infarction may be potentially dangerous and so predictable.Method： 42 cases of patients with lacunar infarction,in which 18 cases with hypertension,4 cases with type 2 diabetes,12 cases complicated with hypertension and type 2 diabetes.Application 1.5TMR in all cases,and SWI sequences by conventional MRI imaging examination,combined with clinical data for analysis.Result： 23 cases of cerebral infarction in patients with intracerebral hemorrhage have microbleedings,which on SWI was spot-on,round,oval-shaped low signals.A total of 266 lesions,and the diameter of 1.8mm-7.4mm.Micro-bleeding points distributed in the cortex,subcortical,basal ganglia,thalamus,brain stem,and cerebellum.Conclusion： SWI in the detection of cerebral micro-hemorrhage has obvious advantages.For the existence of cerebral infarction patients,SWI can be sensitive to the display of the brain micro-bleeding points,and the clinical application of treating cerebral infarction defibrase provide an easy reference.
