High dose peripheral contrast-enhanced MR angiography (CE-MRA) is losing attractiveness due to advances in MR hardware and software as well as complications associated with gadolinium-based contrast agents . We describe a novel fully digital MR architecture with intrinsically higher signal-to-noise ratio coils that was used to to improve 1) anteroposterior coverage, 2) acquisition resolution, and 3) to reduce contrast agent dose from a double to a single dose. At the same time good image quality was preserved, both by subjective and objective image quality measures.
