Imaging peripheral arterial disease (PAD) in diabetic
patients is challenging. We evaluate a combined QISS MRA
and QISS arterial spin labeled MRA approach (cQISS MRA)
for imaging from the infrarenal aorta to the pedal
vessels in 15 diabetic patients with symptomatic PAD,
using digital subtraction angiography as the reference
standard. High diagnostic confidence was observed for
cQISS-MRA, however this was significantly lower in the
foot compared to more proximal regions. 74.7%
sensitivity and 86.8% specificity for hemodynamically
significant (≥50%) stenosis was observed overall, with
highest sensitivity and specificity for the pelvic
region, and poor specificity (50%) for the pedal region.
