R2 (1/T2) and R2* (1/T2*) are useful metrics related to tissue iron loads. Clinical iron estimation at 3T is limited by the achievable echo times in Cartesian spin echo and gradient echo imaging. We present a modified CSI spectroscopy sequence robust to motion for high SNR liver R2* estimation with the potential for simultaneous R2 estimation.
