Compressed sensing and parallel imaging are combined into a single joint acceleration approach for highly accelerated 3D first-pass cardiac perfusion MRI. 3D perfusion imaging is a natural candidate for this combined approach, due to increased sparsity and incoherence provided by the high dimensionality of the data, multi-dimensional acceleration capability and increased baseline SNR. We demonstrate the feasibility of high in vivo acceleration factors of 16 for 3D first-pass cardiac perfusion MRI studies with whole-heart coverage per heartbeat using a 32-element coil array
