Phosphorus and particularly phosphocreatine play a
crucial role in physiological processes such as the
human energy metabolism. Since the
in
vivo
MR
signal of
31
P
is four orders of magnitude smaller compared to
hydrogen, new acquisition strategies to improve the SNR
are required. In this work, the human calf was examined
applying a radially sampled and density adapted
screening combined with several fbSSFP sequences. The
highest SNR was achieved for a positive followed by a
negative radially sampled gradient acquiring two
contrasts.
