Synopsis

In this abstract, we report the reproducibility of the new 31P-MRF technique on healthy volunteers. We show that relaxation and concentration rates can be estimated fast and accurate in good agreement with state-of-the-art methods in the human brain and in phantoms at 7T. This novel efficient technique is able to achieve a 5-fold acquisition time reduction of 31P relaxation parameter measurements, using only 6 min scan time.
