Performing 3D cardiac CINE imaging in a single breathhold is challenging due to the long acquisition times required to collect the necessary data. By employing 3D through-time radial GRAPPA, a method similar to the 2D radial GRAPPA method introduced for real-time cardiac imaging, highly accelerated 3D CINE stack-of-stars radial data can be reconstructed. This abstract demonstrates that by using 3D through-time radial GRAPPA, data for 3D cardiac CINE images that cover the entire heart can acquired within a 15 second breathhold with a temporal resolution of 45 ms per 3D volume and a spatial resolution of 2.3x2.3x6 mm3.
