Conventional contrast-enhanced peripheral MR angiography (MRA) typically uses subtraction-based methods, which reduces the signal-to-noise ratio and can be adversely affected by patient motion. The purpose of this study is to investigate the use of a time-resolved, non-subtractive method for MRA in 20 patients with peripheral vascular disease. Two-point Dixon non-subtractive MRA uses a dual-echo sequence to produce fat- and water-separated images. This method removes bright fat signal from the angiograms without the use of subtraction.
