title: Two-volume acquisition in image-guided proton spectroscopy.
abstract: By combining two-frequency excitation with 1H 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 1H NMR brain spectroscopy. First results with a tumor patient are also presented.
