SPAIR fat suppression technique preserves the contrast, but is sensitive to B0 inhomogeneity. Compared to SPAIR, STIR is a robust fat suppression method, but the image contrast will be affected by the inversion recovry procedure. In this work, a new concept is presented, to Complementarily Use SPAIR in the homogeneous regions and short T1 selected inversion Recovery in the inhomogeneous regions for uniform fat suppression in a single acquisition in SPACE, to preserve good contrast in the main region of the FOV and achieve uniform fat suppression in whole FOV.
