T1rho is a valuable biomarker to probe macromolecular components in tissue. However, conventional T1rho quantification techniques are susceptible to B1 RF and B0 field inhomogeneities, which cause failure of spin-lock and signal oscillation. Adiabatic pulses have been used before and after spin-lock for simultaneous B1 RF and B0 field inhomogeneities compensation and have achieved robust spin-lock, but it does not remove the effect of field inhomogeneities to the actual T1rho value. Therefore, robust T1rho quantification still remains a problem. In this work, we utilized AC-iTIP and combined it with a proposed correction method to address this problem.
