By combining two‐frequency excitation with 1 H NMR STEAM spectroscopy, it is possible to measure two volumes of interest simultaneously without an increase in measuring time compared to single‐volume STEAM. Spatial selectivity and spectral resolution of this approach are demonstrated for test solutions and for human 1 H NMR brain spectroscopy. First results with a tumor patient are also presented. © 1990 Academic Press, Inc.
