Abstract
In vivo proton magnetic resonance spectroscopy studies of gastrocnemius muscle were performed in six normal volunteers. Both spatially resolved spectroscopy (SPARS) and stimulated echo acquisition mode (STEAM) sequences were used for volume localization. A number of water suppression sequences have been combined with these localization schemes. Among the various techniques investigated in these studies, STEAM with an inversion pulse (T1 ‐discriminated spectrum) seems to have the best potential for in vivo localized high‐resolution proton spectroscopy studies of human muscle. © 1988 Academic Press, Inc.
