MRI

The use of cardiovascular MRI in peripheral arterial disease is outlined.

ACC/AHA Guidelines- ACCF/ACR/AHA/NASCI/SCMR 2010 Expert Consensus Document on Cardiovascular Magnetic Resonance: Recommendations for Peripheral artery disease (DO NOT EDIT)

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 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
• Contrast angiography
