Spectral resolution in clinical magnetic resonance spectroscopy

Abstract

We observe linewidths of 0.1–0.4 ppm in ³¹P spectra of human muscle, liver, and brain. T₂ measurements of muscle phosphocreatine, together with previous brain studies, indicate that further improvements in linewidth to 0.02–0.05 ppm might often be achieved, but in same lesions magnetic susceptibility variations may limit spectral resolution. © 1987 Academic Press, Inc.
