Phosphorus (31P)-containing biomolecules play a crucial role in the energy metabolism of all cells. Since the in vivo MR signal of 31P is four orders of magnitude smaller compared to hydrogen, strategies to improve the signal-to-noise (SNR) are required. Therefore, this study focuses on the development of a signal-effective 31P acquisition in combination with a constraint iterative reconstruction applying prior knowledge from recorded hydrogen (1H) data.
