Continuously moving table (CMT) MRI is an efficient whole-body (wb) imaging technique for screening-type applications, which provides spatially and temporally continuous images. However, CMT-MRI has to pay careful attention to fat suppression because the rationale behind the conventional fat suppression approaches, including short tau inversion recovery (STIR) and fat saturation, is not applicable to the CMT cases. In this abstract, we propose an expansion of the GR technique for CMT sequences and compare it with other fat suppression techniques to demonstrate the efficiency of the GR algorithm for fat suppression.
