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。
Abstract
Objective: To evaluate the clinical value of 640-slice spiral CT angiography(CTA) and 3.0T dynamic MR angiography(CE-MRA) in the diagnosis of spinal vascular malformations. Methods: Nineteen cases of clinically suspected spinal vascular disease patients, including 11 cases with CTA examinations, 10 patients with CE-MRA examination, 16 with DSA treatment and 3 with surgery were studied. Results: Four of the 11 cases with CTA examinations were SDAVF, 4 were PMAVF and 2 were SCAVF. Eight were consistent with the DSA diagnosis, and the DSA of one case was negative. Seven of the 10 cases with MRA examinations were SDAVF, in 2 of which CTA examinations did not display the artery and the fistula, but CE-MRA showed the artery and the fistula well. Two cases were PMAVF and 1 case was SCAVM, all consistent with the DSA diagnosis. Conclusion: 3.0T CE-MRA is better than CTA in displaying the spinal vascular malformations artery and fistula, and in diagnosing of spinal vascular malformations. CTA spinal angiography has a great value in the diagnosis of the spinal vascular malformations, and can be used as a screening examination prior to the DSA to guide the DSA. While 3.0T CE-MRA can display the spinal vascular malformations artery and fistula quickly, noninvasively and clearly. CTA and CE-MRA are of great value in diagnosing the spinal vascular malformations, in assisting determining the treatments and in the follow-up visits, etc.
