All imaging was performed on a 1.5 T MRI system with fast gradients (Signa LX; GE Healthcare, Waukesha, WI). Images were acquired with a novel technique that combined undersampled PR with a time\u2010resolved acquisition to yield an MRA method with high temporal and spatial resolution. The method is called PR hyper time\u2010resolved imaging of contrast kinetics (PR\u2010hyperTRICKS). Quantitative and qualitative analyses were used to compare two\u2010dimensional (2D) time\u2010of\u2010flight (TOF) and PR\u2010hyperTRICKS in 13 arterial segments per lower extremity. Statistical analysis was performed with the Wilcoxon signed\u2010rank test.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fifteen percent (77\/517) of the vessels were scored as missing or nondiagnostic with 2D TOF, but were scored as diagnostic with PR\u2010hyperTRICKS. Image quality was superior with PR\u2010hyperTRICKS vs. 2D TOF (on a four\u2010point scale, mean rank = 3.3 \u00b1 1.2 vs. 2.9 \u00b1 1.2, <jats:italic>P<\/jats:italic> &lt; 0.0001). PR\u2010hyperTRICKS produced images with high contrast\u2010to\u2010noise ratios (CNR) and high spatial and temporal resolution. 2D TOF images were of inferior quality due to moderate spatial resolution, inferior CNR, greater flow\u2010related artifacts, and absence of temporal resolution.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>PR\u2010hyperTRICKS provides superior preoperative assessment of lower limb ischemia compared to 2D TOF.
