Simultaneous localized 1H STEAM/31P ISIS spectroscopy in vivo.
A sequence for simultaneous acquisition of 1H STEAM and 31P ISIS spectra is described, and 1H and 31P spectra obtained simultaneously from the same volume of interest in both a phantom and a volunteer are presented. The STEAM and ISIS parts of the sequence use a common gradient scheme that is also used during the localized shimming process, partially compensating for eddy current effects. It is demonstrated that this method of simultaneous multinuclear spectroscopy does not compromise the localization performance of the sequence.
