Steady-state free precession (SSFP) techniques are sensitive to the frequency offset caused by field inhomogeneity. In this study we demonstrated the influence of off-resonance effects on the estimation of MRI-dependent tissue parameters obtained from SSFP techniques. If the field inhomogeneity caused by tissue susceptibility can not be neglected, errors in the parameter estimation can be reduced by measuring data at various frequency offsets in order to find the optimal estimate.
