The 2-point Dixon and Homodyne method each rely on
certain assumptions of the underlying phase in the image
to work correctly. Here we analyze a published method of
combining both reconstruction techniques into one,
effectively performing fat/water separation while
regaining lost resolution from a partial k-space
acquisition. New echo times with improved phase
characteristics are proposed which are shown to reduce
the artifact associated with the method. The Homodyne
Dixon method along with the new echo time choice can
enable improved temporal or spatial resolution in
time-sensitive scans such as DCE or breath hold imaging.
