3.0T 三维动态增强MR血管成像诊断脊髓血管畸形

目的 评价3.0T MR脊髓三维动态增强MR血管成像(CE-MRA)诊断脊髓血管畸形的临床价值。方法 对临床及MR平扫疑诊脊髓血管病的14例患者行CE-MRA检查,其中13例于3~5天内接受DSA检查,6例接受手术治疗,对比分析MRA与DSA及手术结果。结果 CE-MRA诊断8例为硬脊膜动静脉瘘(SDAVF),5例为髓周动静脉瘘(PMAVF),1例为脊髓动静脉畸形(SCAVM);与DSA检查结果对照,14例中,MRA可以准确判断11例的供血动脉及瘘口。结论 3.0T 3D-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,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。

3.0T three-dimensional contrast-enhanced MR angiography in diagnosis of spinal vascular malformations

Objective To explore the value of three-dimensional contrast-enhanced MR angiography (3D-CE-MRA) using 3.0T MR scanner in the diagnosis of spinal vascular malformations. Methods Fourteen patients with suspected spinal vascular diseases by initial MRI and clinical manifestations underwent 3D-CE-MRA, among them 13 underwent DSA within 3-5 days, 6 finally underwent surgical operation. The results of MRA and DSA or surgical findings were compared. Results CE-MRA diagnosed spinal dural arteriovenous fistula (SDAVF) in 8 patients, perimedullary arteriovenous fistula (PMAVF) in 5 patients, and spinal cord arteriovenous malformations (SCAVM) in one case. Compared with DSA, the fistula and feeding vessels were accurately showed in 11 of 14 cases with MRA. Conclusion Spinal angiography with 3D-CE-MRA using 3.0T MR scanner can clearly show the feeding arteries and the location of fistula of spinal vascular malformations, which plays an important role in the diagnosis, treatment and postoperative follow-up of these diseases.
