A system and method of use includes (a) directing a magnetic resonance (MR) system to perform a pulse sequences block in which radio frequency (RF) energy is applied to the subject to substantially saturate magnetization corresponding to an exchangeable proton. The method includes (b), following step (a), acquiring data from the subject with the MR system and (c) repeating step (a) a plurality of times where parameters of the pulse sequence sub-block differ in at least some pulse sequence sub-blocks by at least an amount of RF energy applied to saturate the magnetization. The method further includes (d), after each repetition of step (a), repeating step (b) to acquire data representing signal evolutions from the subject. Additionally, the method includes (e) comparing the signal evolutions with a dictionary database comprising a plurality of different signal evolution templates to determine quantitative chemical exchange or exchangeable proton information of the subject.
