Non-gadolinium-enhanced magnetic resonance angiography (nMRA) is a noninvasive, contrast-free imaging modality used for visualizing pedal arterial anatomy. We report application of the nMRA technique for detailed arterial imaging in a patient with dorsalis pedis aneurysm. Compared with digital subtraction angiography, we demonstrate that nMRA provides sufficient arterial detail needed to develop a complex operative plan before vascular intervention without risk of contrast agent or ionizing radiation exposure.
非钆增强磁共振血管造影（nMRA）是一种用于可视化足部动脉解剖结构的无创、无需造影剂的成像方式。我们报告了nMRA技术在一名患有足背动脉瘤患者的详细动脉成像中的应用。与数字减影血管造影相比，我们证明nMRA提供了在血管介入前制定复杂手术计划所需的足够动脉细节，且无造影剂或电离辐射暴露风险。
