Phase-cycling (PC) has been proposed as an effective method to minimize the impact of B0 and B1 field inhomogeneities in quantitative T1rho mapping, which needs both positive and negative longitudinal magnetization T1rho preparations. We propose here a simple magnetization inversion with an adiabatic inversion RF pulse before an established T1ρ preparation module to achieve an opposite PC. This approach has been shown to be much less sensitive to B0/B1 field imperfections compared with a traditional approach of reversing the phase of the last 90° RF pulse.
