In the abstract we have implemented a novel blood suppression method called DANTE preparation pulses in coronary artery studies. It supposed to be able to generate high contrast images while maintaining SNR. We have tested its performance with 2D multi-slice and 3D spiral GRE sequences. Traditional double inversion recovery sequence was provided as a reference. The results show that CNR in DANTE prepared images is higher than the ones with DIR, with little SNR loss, and with DANTE pulses, the imaging strategy is more flexible and robust.
