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.
