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.
