Atherosclerotic disease of the peripheral vasculature is a prevalent condition for which catheter-based techniques have been considered to be the gold standard for diagnosis. However, because of their invasive nature, these techniques inherently have the potential for complications. Non-invasive diagnostic techniques have historically been limited by low accuracy and high operator dependence. Magnetic resonance angiography (MRA) is a new approach that has diagnostic accuracy comparable with invasive angiography.
The literature on MRA for evaluation of carotid, mesenteric, renal, and lower-extremity arterial disease was extensively reviewed. Helpful diagnostic algorithms on the basis of the literature are also provided.
MRA is both sensitive and specific when compared with invasive angiography for the evaluation of peripheral arterial disease and avoids the potential for complications resulting from arterial puncture and use of iodinated contrast.
Current MRA techniques are diagnostically robust and have proven to be a highly accurate, safe, and convenient means of diagnosing atherosclerotic disease of the peripheral vascular system.
外周血管系统的动脉粥样硬化疾病是一种常见病症，基于导管的技术一直被视为诊断的金标准。然而，由于这些技术具有侵入性，它们本质上存在并发症的可能性。历史上，非侵入性诊断技术一直受到准确性低和操作者依赖性高的限制。磁共振血管造影（MRA）是一种新方法，其诊断准确性与侵入性血管造影相当。
广泛回顾了关于MRA评估颈动脉、肠系膜动脉、肾动脉和下肢动脉疾病的文献。还根据文献提供了有用的诊断算法。
与侵入性血管造影相比，MRA在评估外周动脉疾病时既敏感又特异，并且避免了动脉穿刺和使用碘化造影剂导致的并发症可能性。
当前的MRA技术诊断能力强大，已被证明是诊断外周血管系统动脉粥样硬化疾病的一种高度准确、安全且便捷的方法。
