Preferred Abstract (Original): 

The aim of this study was to assess a venous compression technique that is performed with contrast material– enhanced peripheral magnetic resonance (MR) angiography to reduce venous enhancement. Healthy volunteers, as well as patients with correlating digital subtraction angiographic (DSA) findings, were examined. Venous compression was accomplished by placing a cuff at the midfemoral level unilaterally. Arterial signal-tonoise and contrast-to-noise ratios indicated no significant differences between compressed and noncompressed legs. Venous overlay was substantially reduced in the compressed legs. MR angiography with venous compression yielded diagnostic image quality and results that had excellent correlation with DSA findings. High-spatial-resolution peripheral MR angiography of improved diagnostic quality appears feasible, even with long data acquisition times
