This work presents quantitative T2-maps and a full T2w-image series generated from an ordinary single contrast T2w-dataset using the growing Constrained Alternating Minimization for Parameter mapping (g-CAMP) reconstruction method. Simulated data were used to study the accuracy of this approach under various echo spacings and with added noise, and the method is also demonstrated in an experimental T2w-dataset. This could ultimately lead to retrospective parameter mapping using data from standard single-contrast acquisitions.
