During the long phase encoding of sodium CSI measurements, due to hardware constraints on common whole-body scanners, signal significantly decays meanwhile no data acquisition is possible. Thus, the presented work describes a 3D chemical shift imaging (CSI) sequence with individually minimized phase encoding durations for sodium MRI. In an additional experiment, CSI data is acquired with a Hanning weighted pre-filter and both approaches are compared to the radial projection imaging technique.
