In this work, we demonstrate whole-body fat/water separation at 3 Tesla using a 90 second multiecho Continuously Moving Table (CMT) MRI scan based on a golden angle (GA) radial sampling pattern. GA sampling allows retrospective profile binning for arbitrary slice thickness reconstructions and high degrees of radial under-sampling without coherent image artifacts. This allows the collection of 4 echoes per TR for accurate fat/water separation, as well as whole-body ΔB0 and R2* mapping. We demonstrate high-quality whole-body (1.8 m Z direction coverage) fat/water separation with this technique in a rapid 90-second scan.
