Fast spin-echo images contain artifacts related to relaxation and imperfect refocusing. These artifacts are explained by well-known signal equations, and the sources of these artifacts can be accounted for if fit as a free parameter during image reconstruction. This abstract demonstrates the potential of this approach for artifact-free T2 mapping in comparison maps derived from Fourier-reconstructed images and voxelwise parameter fits.
