Dynamic contrast-enhanced lung imaging, with high resemblance with dynamic cardiac imaging for having high intensity variation constrained in relatively limited image space together with corresponding sparsity in the corresponding x-f space, may serve as a potential candidate for the CS techniques. This work shows while k-t BLAST was shown to be a well-performing alternative for dynamic CE lung imaging [4], CS may also be an encouraging candidate as it slightly outperforms k-t BLAST while remaining relatively stable in different phases
