Quantitative imaging promises to be a good biomarker of disease but requires long acquisition times, especially when 3D acquisition techniques are used. Here we propose to use a highly undersampled 3D phase-cycled balanced steady-state free-precession sequence in combination with the reconstruction methods MIRACLE and trueCISS, providing quantitative maps (T2,T1,M0). Additionally, synthetic contrasts can be generated using the previously calculated quantitative maps and signal models, exemplarily shown for bSSFP, T2- and T1-weighted contrast. In summary, the proposed method provides a set of quantitative maps and various conventional contrasts using a single 3:31min acquisition.
