SPACE employs non-selective RF pulses to achieve short
echo spacing in the imaging with long echo trains.
However, the use of non-selective RF pulses results in a
single slab acquisition in SPACE imaging. In typical
SPACE protocols, the duration of the echo train is only
about 20% of the TR, which means 80% of the time is
purely for waiting. In order to improve the time
utilization ratio, in this work, we investigate the
feasibility of acquiring a second contrast in the
waiting time of the TR in single slab SPACE imaging.
Some preliminary results of the hybrid imaging are
shown.
