title: Residual dipolar coupling of the Cr/PCr methyl resonance in resting human medial gastrocnemius muscle.
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 ( approximately 34 msec) dipolar dephasing and a less rapid ( approximately 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.
