探讨磁共振高信号血管征对诊断急性脑梗死的临床意义

To explore the clinical significance of high signal vessel sign of magnetic resonance in the diagnosis of acute cerebral infarction

目的:观察磁共振高信号血管征对诊断急性脑梗死的临床意义。方法:将我院于2018年2月至2019年2月阶段收治的300例急性脑梗死患者作为研究对象,对所有患者行MRI和MRA检查,将高信号血管征和MRA,DWI序列高信号病灶进行比较。结果:300例患者中,出现高信号血管征患者共计100例,出现率为33%,其中前循环异常信号为80例,后循环异常信号为20例,特异度分别为95%,88%。结论:磁共振高信号血管征对诊断急性脑梗死患者具有较高的准确率,可为急性脑梗死患者颅内血管狭窄或者闭塞提供一定的参考价值,具有一定的推广价值。若具有高信号血管征的提示,应及时采取有效的措施对患者进行治疗。

Objective To observe the clinical significance of high signal vessel sign of magnetic resonance in the diagnosis of acute cerebral infarction.Methods 300 patients with acute cerebral infarction admitted to our hospital from February 2018 to February 2019 were studied.All patients were examined by MRI and MRA.The high signal vessel signs and MRA,DWI high signal lesions were compared.Results Among the 300 patients,100 cases had high signal vessel sign,the occurrence rate was 33%.Among them,80 cases had abnormal signal of anterior circulation,20 cases had abnormal signal of posterior circulation,and the specificity was 95%and 88%respectively.Conclusion The high signal vessel sign of magnetic resonance has a high accuracy in the diagnosis of acute cerebral infarction,which can provide some reference value for the diagnosis of intracranial vascular stenosis or occlusion in patients with acute cerebral infarction,and has a certain popularization value.If there is a sign of high signal vessels,effective measures should be taken to treat the patients in time.
