This study shows preliminary results of the feasibility using MRS-FP to measure the relaxation parameters of γ-ATP and PCr as well as the chemical exchange rate k_CK. All results were in good agreement with literature values enabling a fast and robust 31 P multi parameter estimation in vivo human brain at 7T .
