During application of DANTE (a rapid series of low flip angle RF pulses interspersed with gradients)pulse trains, longitudinal magnetization of flowing spins is largely (or fully) attenuated. This is in contrast to static tissue, whose longitudinal magnetization is mostly preserved. DANTE may be well suited for mutilslice imaging acquisition. This work is to introduce this novel approach to fast black blood imaging. It was found that the overall improvement of the DANTE method over the existing methods is approximately factor of 2.
