Spiral in-out readout is an efficient sampling scheme for T2-weighted (T2w) spin-echo (SE) sequences. Two sets of spiral in-out data at different TEs are typically acquired so that deblurred water and fat images can be extracted from the spiral-in and the spiral-out data separately, which are then combined together. A method has been recently proposed to reconstruct water and fat images from a single set of spiral in-out data. This work demonstrates the feasibility of using this method as a fast and scan efficient means of fat suppression to reduce the scan time of the spiral T2w SE by a factor of 2.
