The self-navigating property of radial imaging has been exploited in various motion correction methods. However, there is always a tradeoff between the robustness and temporal resolution of motion correction. In this work, a recently proposed rapid parallel imaging method, GRAPPA operator for wider radial bands (GROWL), is applied to increase the temporal resolution of motion correction in multi-coil radial imaging applications. It is demonstrated that robust in-plane rotation/translation motion detection and correction can be achieved with as few as 8 radial views using an 8-channel coil.
