Spinal cord arteries and veins are difficult to visualize and distinguish by MR angiographic techniques because of their small sizes, similar spatial course, and close vascular anatomy. Contrast-enhanced MR angiography was demonstrated to dynamically resolve the Adamkiewicz artery from the anterior radiculomedullary vein in the thoracolumbar spinal cord. The location of the Adamkiewicz artery and the anterior radiculomedullary vein could be validated in the postmortem specimen of a thoracoabdominal aortic aneurysm patient.
脊髓动静脉由于其管径小、空间走行相似以及血管解剖结构紧密,通过磁共振血管造影技术很难可视化和区分。对比增强磁共振血管造影被证明能够动态区分胸腰段脊髓中的Adamkiewicz动脉和前根髓静脉。Adamkiewicz动脉和前根髓静脉的位置可以在一名胸腹主动脉瘤患者的尸检标本中得到验证。
