Uniform fat suppression is critical for optimal MR assessment of lesions in the abdomen and pelvis. Recent advances using SPAIR sequencing have improved fat suppression and increased the signal-to-noise ratio versus older techniques. However, fat suppression still remains challenging in anatomical regions away from the magnetic isocenter due to field inhomogeneity. Here we demonstrate that continuous table movement (CTM) is superior to fixed table (FT) technology for SPAIR-mediated fat suppression across the entire image stack. As field inhomogeneity away from isocenter is a common challenge, CTM may provide a solution to many frequently encountered problems.
