This paper describes a new clinical spectroscopy pulse program, hydrogen ultrathin phase‐encoded spectroscopy. This sequence combines high spatial resolution with magnitude hydrogen spectroscopy. A linear volume is spatially frequency encoded with a conventional readout gradient and phase encoded spectrally by incrementing the timing of acquisition. The pulse sequence is implemented on a whole‐body MRI scanner and supports several standard scanner options, including autoprescanning, offset of the center of field of view in the frequency‐encoding direction, and oblique imaging. Some preliminary experimental experience is reported, demonstrating the possibility of observing the spectral line widths of fat and water in marrow, and of observing the spectral line widths of fat and water in marrow, and of observing multiline spectra. Combination of the technique with water suppression methods in a sequence called WASHUP is also discussed © 1990 Academic Press, Inc.
