摘要
目的评价MRI对椎管内动静脉血管畸形的诊断价值。方法回顾性分析手术及DSA证实的12例椎管内动静脉畸形(AVM)的MRI资料。结果椎管内AVM根据部位分为髓内AVM,硬膜内髓周AVM及硬脊膜动静脉瘘(AVF)。MRI表现为脊髓增粗,髓内或髓周密集的血管流空影,同时可显示出血及脊髓内的软化或水肿。结论MRI是评价椎管内AVM十分敏感和有效的方法。
Objective To evaluate the value of MRI in diagnosis of intraspinal arteriovenous ma lformation.Methods MRI findigs of intraspinal AVM by pathology and DSA proved in 12patients were analyzed.Results According to the location,intraspi nal arteriovenous malformation were divided into thre e types:intramedullary AVM,perime dullary AVM and dural arteriovenous fistulae.MRI features were enlargment of the spinal cord,flow v oid signal in inside or outside of spi nal cord,hemorrhage,edema and myel omalacia in the spinal cord.Conclusion MRI is very sensitive and effective means for evaluating intraspinal arteriovenous malformation.[
