Synopsis

Keywords: Spectroscopy, Spectroscopy, Lipid Fat Suppression RemovalWe present an elegant and easy to implement method for MRI and CSI steady-state sequences to remove or suppress lipids or other components with short transverse relaxation times by neither introducing additional pulses nor hardware and by just altering the excitation pulse phase.
