3.0T磁共振高分辨磁敏感成像在血管畸形中的应用价值

The clinical application of high-resolution susceptibility weighted imaging in diagnosis of brain vascular malformation at 3.0T MRI

目的:探讨高分辨磁敏感成像(HR-SWI)在脑部血管畸形中的应用价值。方法:对45例脑血管畸形的患者行常规MR序列和HRSWI扫描。其中8例同时行MRA检查,31例行增强检查。结果:45例患者均在HR-SWI上清晰显示畸形血管,其中海绵状血管瘤26例,动静脉畸形5例,静脉瘤11例,Sturge-Weber综合征3例。结论:SWI显示血管畸形更清晰,明显优于常规序列,可为临床提供更多有用的信息并有助于脑血管畸形的确诊。

Objective：To study the value of high-resolution susceptibility weighted imaging（HRSWI） in the brain vascular malformations.Methods： HRSWI and conventional MR sequences was performed in 45 patients with brain vascular malformations.Of all patients,8cases underwent MRA and 31 cases underwent contrast-enhanced T1-weighted imaging.Results： 45 cases of brain vascular malformations appear clearly in HRSWI,including of 26 cases of cerebral cavernous angioma,5 cases of arteriovenous malformation,11 cases of venous malformation and 3 cases of Sturge-Weber syndrome.Conclusion：HRSWI appears brain vascular malformations clearly and superior to conventional MR sequences.HRSWI provide addioional clinically useful information in the evaluation of brain vascular malformations and can help confirm the diagnosis.
