High-resolution Steady-State (SS) imaging of arterial territories are successfully implemented as an adjunct to first-pass (FP) acquisition, thanks to the introduction of blood-pool agents (BPa); nevertheless, BPa are expensive and not widely available. For this reasons we tested the potential of gadobenate dimeglumine (MultiHance) for high resolution SS imaging as an addition to conventional FP CE-MRA for the detection of relevant stenosis of the carotid arteries. Our study demonstrates that the increased spatial resolution attainable on SS images combined with the elevated contrast enhancement of MultiHance permits improved detection of arterial stenoses, with diagnostic performance comparable to CTA and DSA.
