Combinations of PROPELLER and Dixon methods have
recently been proposed to achieve motion insensitive
water-fat imaging. They perform the water-fat separation
after the PROPELLER reconstruction so far. However,
applying the water-fat separation to single blades
instead potentially offers several advantages. In this
work, the feasibility of this approach is demonstrated
in abdominal T2-weighted TSE imaging. By exploiting the
Cartesian k-space sampling in single blades, an
off-resonance correction for image quality enhancement
is shown to become simpler in this way.
