Our objective was to determine whether a rapid, non-contrast MRA technique might provide superior accuracy to ABI and reduce the need for additional imaging procedures prior to a revascularization procedure. Using CE-MRA as the reference standard, the sensitivity and specificity of ABI and non contrast QISS MRA for 50% or greater stenosis or occlusion was determined.
