Potassium ions are of fundamental importance in the
physiology of living organisms. In human thigh muscle
oscillations in the T

of

K
MR-signal have been observed. To investigate this
effect, in vivo spectra of potassium and for comparison
of sodium were acquired. The
39
K
spectrum of a human thigh muscle shows triplet
splitting. Its peaks were quantitatively analyzed with
the AMARES algorithm and led to results in agreement
with the theory of quadrupolar splitting due to
anisotropy.
