Recommendations
1 B-NR
1. In patients with functionally limiting claudication with
inadequate response to GDMT (including structured
exercise) for whom revascularization is being considered,
duplex ultrasound, computed tomography angiography
(CTA), magnetic resonance angiography (MRA), or catheter
angiography of the lower extremities is useful for assessment
of anatomy and severity of disease and to determine potential
revascularization strateg y.

2. In patients with CLTI, duplex ultrasound, CTA, MRA, or
catheter angiography is useful to determine revascularization
strateg y.
2b C-EO
3. In patients with suspected PAD (ie, potential signs and/or
symptoms) with inconclusive ABI and physiological testing,
noninvasive imaging with duplex ultrasound, CTA, or MRA
may be considered to establish the diagnosis of PAD.
3: Harm B-NR
4. In patients with a confirmed diagnosis of PAD in whom
revascularization is not being considered, CTA, MRA, or
catheter angiography should not be performed solely for
anatomic assessment.
