CMR for PAD
Level of Evidence: A). CMR of the extremities may be considered
(Class IIb, Level of Evidence: B); and
IIb, Level of Evidence: B). Additionally, MRA of the lower extremities is appropriate for patients with claudication. |

- Magnetic resonance angiography is the most sensitive modality to make this diagnosis of PVD.
- Magnetic resonance angiography
- Benefits:
- Useful to asses PAD anatomy and presence of significant stenoses
- Useful to select patients who are candidates for endovascular or surgical revascularization
- Limitations:
- Tends to overestimate the degree of stenosis
- May be inaccurate in arteries treated with metal stents
- Can not be used in patients with contraindications to the magnetic resonance technique
- Benefits:
- Contrast angiography
