Abstract
This paper presents a detailed analysis of the TE dependence of the creatin e methyl proton signal at 3.02 ppm, resulting from a symmetric PRESS sequen ce applied to the resting human gastrocnemius muscle. The analysis shows th at a two-component decay of the central peak of the dipolar-coupled-methyl triplet should be interpreted as the superposition of a rapid (approximate to 34 msec) dipolar dephasing and a less rapid (approximate to 162 msec) tr ansverse relaxation. These data do not support a two-pool hypothesis for TE dependence of this signal. (C) 1999 Wiley-Liss, Inc.
