For applications like dynamic imaging, the relatively fast decaying hyperpolarized signal must be acquired over a higher number of sequence cycles and the optimal refocusing flip angle needs to be determined. Optimizing the RARE refocussing flip angles allow to optimize the signal exploitation. Furthermore, optimizing the flip angles of a RARE-based varying flip-angle TRAPS sequence enables an even longer prolongation of the signal lifetime.
