Despite its successful application to detect many pathological disorders in brain [1, 2], breast [3] and prostate [4], Localized Correlated Spectroscopy (L-COSY) still suffers from long acquisition that prevents this technique to enter clinical studies [5]. Inherent sparse nature of L-COSY can be exploited to accelerate the long acquisition times ensued from iterative sampling along indirect dimension (t1). In this study, a new reconstruction strategy is presented that takes the advantage of sparsity to reconstruct the whole L-COSY spectrum with less number of acquisitions along the t1 dimension.
