Rapid image acquisition is required to assess myocardial first-pass perfusion. K-t CS which uses compressed sensing has produced dynamic images with sufficient resolution. View sharing methods such as k-t VS could potentially provide similar results eliminating the need for regularization weights and significantly decreasing reconstruction time. K-t CS and k-t VS were investigated to determine their temporal and spatial response during first-pass myocardial perfusion. Results demonstrate that images reconstructed using each method had similar resolution and showed good correlation in assessing uptake kinetics. However, at higher acceleration, k-t CS showed increased SNR and smoother appearance while k-t VS used a less computationally intense and faster reconstruction.
