Abstract
This paper presents a detailed analysis of the TE dependence of the creatine methyl proton signal at 3.02 ppm, resulting from a symmetric PRESS sequence applied to the resting human gastrocnemius muscle. The analysis shows that a two‐component decay of the central peak of the dipolar‐coupled‐methyl triplet should be interpreted as the superposition of a rapid (≈34 msec) dipolar dephasing and a less rapid (≈162 msec) transverse relaxation. These data do not support a two‐pool hypothesis for TE dependence of this signal. Magn Reson Med 42:421–424, 1999. © 1999 Wiley‐Liss, Inc.
