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, 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.
- 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
