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
