PURPOSE
To determine the potential and limitations of MR angiography in the evaluation of spinal vascular malformations.
METHODS
Eleven consecutive patients with spinal vascular malformations proved with spinal selective arteriography underwent two-dimensional phase-contrast MR angiography.
RESULTS
Abnormal vessels within the spinal canal were identified with MR angiography in 10 patients. In 1 patient with a dural arteriovenous fistula no definite vascular abnormality was seen with MR angiography. Correlation of MR angiography with spinal selective arteriography showed that the former allowed identification of the arterial feeder in 3 patients with intramedullary arteriovenous malformations and 2 with perimedullary arteriovenous fistula, whereas the source of intradural draining vein was seen in only 2 of 6 patients with dural arteriovenous fistula.
CONCLUSION
MR angiography is a promising complementary tool to MR imaging for detection and characterization of spinal vascular malformations.
目的
确定磁共振血管造影在评估脊髓血管畸形中的潜力和局限性。
方法
11例经脊髓选择性动脉造影证实患有脊髓血管畸形的连续患者接受了二维相位对比磁共振血管造影。
结果
10例患者通过磁共振血管造影在椎管内发现了异常血管。1例硬脊膜动静脉瘘患者的磁共振血管造影未发现明确的血管异常。磁共振血管造影与脊髓选择性动脉造影的相关性表明，前者可在3例髓内动静脉畸形和2例髓周动静脉瘘患者中识别出动脉供血支，而在6例硬脊膜动静脉瘘患者中，仅2例可见硬脊膜内引流静脉的来源。
结论
磁共振血管造影是一种很有前景的辅助工具，可用于磁共振成像检测和鉴别脊髓血管畸形。
