Notes: For the abdominal imaging, the heavily T2-weighted (HT2W) volume is acquired as a gated acquisition triggered by a respiratory bellow. The single-shot T2-weighted (SST2W) stack and the balanced fast field echo (BFFE) acquisitions are acquired at separate expiratory breath-holds (BH). For the quasi‐static control brain experiment, no imaging trigger is used and an additional HR T2W volume is acquired for ground-truth comparisons. Example images associated with this protocol are shown in Figure 2.
