Overview
When symptoms suggestive of peripheral artery disease are present, clinical evaluation along with non invasive testing are enough to establish the diagnosis. Invasive diagnostic studies are anatomic studies that are not used for diagnosis but rather for preoperative evaluation of the anatomy of the vessels. The invasive diagnostic studies, which are basically anatomic studies that rely on imaging, include the following: conventional angiography, CT angiography, MRA and duplex ultrasound.[1]
MRI
The use of cardiovascular MRI in peripheral arterial disease is outlined:
- Magnetic resonance angiography is the most sensitive modality to make this diagnosis of PVD.
- Benefits of magnetic resonance angiography:
- Useful to asses PAD anatomy and presence of significant stenoses
- Useful to select patients who are candidates for endovascular or surgical revascularization
- Limitations of magnetic resonance angiography:
- 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

Peripheral Artery Disease (DO NOT EDIT)[3][4]
| Class I |
| "CMR for PAD" |
| "1. Is recommended to diagnose anatomic location and degree of stenosis of PAD. (Level of Evidence: A)" |
| "2. Should be performed with gadolinium enhancement. (Level of Evidence: B)" |
| "3. Is useful in selecting patients with lower extremity PAD as candidates for endovascular intervention. (Level of Evidence: A)" |
| Class IIb |
| "CMR of the extremities may be considered" |
| "1. To select patients with lower extremity PAD as candidates for surgical bypass and to select the sites of surgical anastomosis.(Level of Evidence: B)" |
| "2. For post-revascularization (endovascular and surgical bypass) surveillance in patients with lower extremity PAD (Level of Evidence: B)
Additionally, MRA of the lower extremities is appropriate for patients with claudication." |
Magnetic Resonance Angiography (DO NOT EDIT)[3][4]
| Class I |
| "1. Magnetic resonance angiography of the extremities is useful to diagnose anatomic location and degree of stenosis of PAD. (Level of Evidence: A)" |
| "2. Magnetic resonance angiography of the extremities should be performed with gadolinium enhancement. (Level of Evidence: B)" |
| "3. Magnetic resonance angiography of the extremities is useful in selecting patients with lower extremity PAD as candidates for endovascular intervention. (Level of Evidence: A)" |
| Class IIb |
| "1. Magnetic resonance angiography of the extremities may be considered to select patients with lower extremity PAD as candidates for surgical bypass and to select the sites of surgical anastomosis.(Level of Evidence: B)" |
| "2. Magnetic resonance angiography of the extremities may be considered for postrevascularization (endovascular and surgical bypass) surveillance in patients with lower extremity PAD. (Level of Evidence: B) " |
