ABSTRACT:
An ultra-fast NMR scan includes a preparatory phase, a stabilization phase and a data acquisition phase. Image contrast is enhanced by an inversion-recovery-like preparation phase and this is followed by a set of fast pulse sequences in which magnetization is allowed to stabilize. Image data is then acquired during the final phase using a set of GRASS pulse sequences executed in a centric view order.
