ADVANCE-MRV, a recently described method for non-contrast-enhanced venography, is able to depict veins while suppressing the signal from arteries and static tissues, by subtraction of flow-sensitised images. In regions with low flow dispersion, the venous suppression can fluctuate, leading to non-uniform signal in the venograms. This problem was previously overcome by combining multiple images with differing flow sensitisations. An alternative is to use multiple flow preparations within a single acquisition: this method is demonstrated to improve the consistency of venous suppression and the uniformity of the resultant venograms. Initial patient imaging clearly depicts femoral vein occlusion due to DVT.
