parallel-imaging techniques include the one-dimensional or two-dimensional
acceleration of the data acquisition with Cartesian or non-Cartesian
trajectories. However, state-of-the-art receiver coil arrays with 32 and more
coil elements that are distributed approximately uniformly in space should
also enable a three-dimensional parallel-imaging acceleration, i.e.
simultaneous sparse sampling in all three k-space directions. The purpose of
this study was to demonstrate three-dimensional parallel-imaging acceleration
with high acceleration factors up to 32 based on a three-dimensional radial
gradient-echo sequence.
