摘要 目的探讨MRI和DSA对脊髓血管畸形的诊断价值。方法收集术前行MRI及DSA检查并经手术证实的20例脊髓动静脉畸形患者临床及影像资料对比分析。结果 MRI及DSA检出血管畸形分别为:髓内血管畸形10例和4例;髓内外血管畸形7例和7例;髓外血管畸形3例和3例。结论 MRI可无创性显示病灶内部结构及定性诊断脊髓动静脉畸形,但DSA在明确AVM的供血动脉、瘘口部位、引流静脉、病变范围等优于MRI。因此术前MRI和DSA检查结合可明确脊髓AVM的类型,指导临床治疗。 Aim To evaluate value of MRI and DSA in diagnosis of spinal cord vascular malformatlons.Methods There 20 spinal cord vascular malformatlon cases diagnosed with selective spinal digital subtraction angiography and MRI examination were reviewed.Results Of the 20 cases,10 and 4 intramedullary nidus vascular malformation cases diagnosed by MRI and DSA,7 and 7 intra-and-extra-medullary nidus vascular malformation cases by MRI and DSA,3 and 3 extramedullary nidus vascular malformation cases,respectively.Conclusion It is an ideal non-invasive technique to diagnose spinal vascular malformation with MRI.But DSA is more accurate to demonstrate the feeding arteries,draining veins,arteriovenous fistual,the extent.
