We present results from a rapid, whole-body, free-breathing MR imaging protocol that uses a continuous moving bed coupled with a golden angle radial acquisition and a compressed sensing reconstruction to achieve high image quality and artifact reduction despite an equivalent undersampling factor of 7.0. Additionally, the use of a golden angle radial acquisition allows slice positions and thicknesses to be determined after data collection, allowing the reconstructed images to be tailored to the clinical application so as to minimize through-slice signal averaging effects in regions of interest or control the balance of SNR and spatial resolution.
