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.
