13
C NMR spectroscopy enables a noninvasive
quantification of various metabolites in vivo (without
or with an enrichment of
13
C)
and takes advantage of high B
0
and
of
1
H-decoupling.
The aim of this study was to design, implement and test
a surface coil system for in vivo
1
H-decoupled
13
C
NMR spectroscopy on an experimental 7-T whole-body MR
tomograph. The use of a transmission line resonator
concept with special frequency selective filter circuits
ensures sufficient electromagnetic decoupling for both
frequencies (
13
C,
1
H).
The resulting coil system allows among other
applications the acquisition of high resolution

NMR spectra in vivo.
