Head motion poses a significant problem in MRSI experiments, especially for 1H-MRSI of the brain performed without water or lipid suppression. In this work we propose a practical method specifically designed to track head motion and correct for its effects on 1H-MRSI data acquired without water suppression. By using the companion spectroscopic water signals, we are able to track head motion with navigators collected in circular and linear trajectories. A specialized data processing scheme is also proposed for processing the navigator data along with the unsuppressed spectroscopic water signals to determine the motion parameters.
