Magnetic resonance angiography (MRA) is an alternative for patients who are allergic to iodinated contrast material. MRA is not innocuous. Gadolinium chelates, the contrast agents used in MRA, have been linked recently to 3 potentially serious side effects in patients with renal insufficiency: acute renal injury, pseudohypocalcemia, and nephrogenic systemic fibrosis. MRA is contraindicated in patients with implanted hardware such as a hip prostheses or pacemakers.

The resolution provided by MRA may be inadequate for the vascular surgeon in planning reconstructive procedures, particularly in the smaller infrapopliteal arteries, although MRA technology and contrast agents continue to improve. [10]
