Multiband imaging allows for multiple simultaneously acquired slices, thus giving an SNR benefit over conventional slice selection without potential artifacts from secondary phase encoding. While methods have been shown that can separate the slides using parallel imaging for Cartesian trajectories, these methods are not compatible with non-Cartesian sampling. Here we demonstrate the possibility of reconstructing two simultaneously acquired radial slices using an acquisition/reconstruction method known as radial CAIPIRINHA. We show that this method is capable of higher accelerations than possible with comparable Cartesian trajectories.
