3D k-space sampling patterns in k y -k z for k-t PCA (a) and k-t SPARSE-SENSE (b). The regular undersampling pattern in k-t PCA is shifted along the temporal dimension using a fixed pattern. In k-t SPARSE-SENSE the sampling is random with high sampling probability density in the k-space centre decreasing towards the edge. The randomness ensures temporal variability of the sampling pattern. 75% partial Fourier sampling was employed along k y and k z in both cases
