Rationale
The original section was extremely brief. Integrating the 2024 PAD guidelines and the 2022 Aortic Disease guidelines provides necessary clinical context, including Class 1 recommendations, the role of non-contrast MRA in renal failure, and the advantage of MRA in reducing radiation exposure for surveillance. All abbreviations were expanded on first use as per instructions.

* AlternativeMagnetic resonance angiography (MRA) is a Class 1 recommendation for the anatomic assessment of lower extremity peripheral artery disease (PAD) when revascularization is planned [@svs2024]. * It serves as an alternative when computed tomography angiography (CTA) is contraindicated (renaldue dysfunction,to renal dysfunction or iodinated contrast allergy).allergy [@svs2024]. * CE-magneticContrast-enhanced magnetic resonance angiography (MRA)(CE-MRA) provides high-resolution images.images for both PAD and aortic disease, including aneurysms and dissections [@aha2022, @svs2024]. * MRA is particularly useful for serial surveillance of aortic disease to minimize ionizing radiation exposure [@aha2022]. * For patients with severe chronic kidney disease (CKD), non-contrast MRA techniques may be utilized to avoid the risk of nephrogenic systemic fibrosis (NSF) associated with certain gadolinium-based contrast agents [@svs2024].
