Rapid 31P spectroscopy on a 4‐T whole‐body system

Initial 31P spectroscopy results from a 4‐T whole‐body system are reported. Localized spectra from the human head, liver, and calf were obtained using DRESS, slice‐inter‐leaved DRESS, and volume 3DFT spectroscopic imaging techniques. Substantial reductions in data acquisition times to 10 s–4 min were achieved relative to previous similar experiments at 1.5 T. Some gain in spectral resolution (as measured in ppm) was also realized in the head. © 1988 Academic Press, Inc.
