FIG. 2.

SI-PRESS sequence with water suppression enhanced through T1 effects (WET) and OVS (eight slabs) for subcutaneous fat suppression, including a coordinate update using the motion tracking data and an IRS sequence block. After the actual acquisition an additional water reference spectrum is acquired without water suppression pulses and using a small excitation angle (10°), but with an otherwise identical sequence block. Since a minimal TR was used for the experiments, the second coordinate update module was merged with the first one from the subsequent average.
