【摘要】:目的:评价640层多层螺旋CT血管成像(CTA)与3.0T动态MR血管成像(CE-MRA)在诊断脊髓血管畸形中的临床应用价值。方法:19例临床怀疑脊髓血管病变的患者,其中11例行多层螺旋CTA检查,10例行CE-MRA检查,16例接受DSA治疗,3例接受手术治疗。结果 :11例行CTA检查中有4例为硬脊膜动静脉瘘(SDAVF),4例为髓周动静瘘(PMAVF),2例为脊髓动静脉畸形(SCAVF),8例与DSA诊断一致,1例DSA为阴性;10例行MRA检查中有7例为SDAVF,其中2例SDAVF CTA检查未显示供血动脉及瘘口,CE-MRA显示很好的供血动脉及瘘口,2例为PMAVF,1例为SCAVF,均与DSA诊断一致。结论:3.0T CE-MRA对显示脊髓血管畸形的供血动脉及瘘口,在诊断脊髓血管畸形中优于CTA;脊髓CTA对脊髓血管畸形的诊断有很大的价值,可作为DSA检查前的筛选检查,并对DSA有指导作用;而3.0T CE-MRA可快速、无创、清晰地显示脊髓血管畸形的供血动脉及瘘口;CTA、CE-MRA在诊断脊髓血管畸形、协助制定治疗方案及术后随访等方面具有重要价值。
