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.
