Diagnosis
Table 9. Imaging for Anatomic Assessment
COR LOE
Recommendations
I B-NR Duplex ultrasound, computed tomography angiography
(CTA), or magnetic resonance angiography (MRA) of the
lower extremities is useful to diagnose anatomic location and
severity of stenosis for patients with symptomatic PAD in whom
revascularization is considered.
I C-EO Invasive angiography is useful for patients with CLI in whom
revascularization is considered.
IIa C-EO Invasive angiography is reasonable for patients with lifestyle-
limiting claudication with an inadequate response to GDMT for
whom revascularization is considered.
III:
Harm
B-R Invasive and noninvasive angiography (i.e., CTA, MRA) should
NOT be performed for the anatomic assessment of patients with
asymptomatic PAD.

Recommendation
IIa B-NR A screening duplex ultrasound for AAA is reasonable in patients
with symptomatic PAD.
