摘要
目的:评价MRI在脑血管畸形诊断中的价值。材料和方法:本文选择经MRI平扫加增强检查,并经过手术、磁共振血管造影(MRA)或数字减影血管造影(DSA)证实的脑血管畸形40例,分析其MRI特征。结果:MRI表现可分为直接征象与间接征象。结论:MRI对脑血管畸形有定性定位诊断价值,特别是适用于血管造影阴性的隐匿性血管畸形。
Objective: To evaluate the magnetic resonance imaging in the diagnosis of cerebral vascular malformation. Materials and Methods: Forty cases received MRI examination, including plain scan and contrast enhancement, and all cases were proved by MRA, USA or surgical procedures. Results: Direct or indirect signs were revealed in MRI scan. Conclusion: MRI is a valuable modality for locative and qualitative diagnosis of the arterialvemous malformations, especiall for the concealed AVM which is usually negative in angiography.
