Recent non-contrast-enhanced vascular imaging methods use velocity-sensitised preparation to suppress vascular signal, combined with subtraction of bright- and dark-blood images to generate angiograms and/or venograms; however separation of arteries and veins is imperfect. In this work, acceleration-dependent preparation was used to suppress arteries, leading to venograms with no apparent arterial contamination.
