This work proposes to employ elastic-net for MRI reconstruction. The elastic net favours grouping effect among the stree-structured wavelet coefficients and thereby yields better reconstruction than straighforward sparse reconstruction. We propose generalization of the standard elastic net formulation by introducing an analysis prior elastic net. The results from our generalization yields better results than state-of-the-art techniques in MRI reconstruction.
