Abstract
A system and method is provided for operating a high-field magnetic resonance (MR) system includes performing a series of data acquisition modules without respiratory gating. Each data acquisition module is formed of a steady-state free precession pulse sequence. Performing the series of data acquisition modules includes varying at least one of an amplitude of an excitation pulse or a repetition time of the steady-state free precession pulse sequence between adjacent data acquisition modules in the series of data acquisition modules to acquire a series of MR data with random or pseudo-random imaging acquisition parameters. The series of MR data is compared to a dictionary of signal evolution profiles to determine a match between the series of MR data with at least one signal evolution profile in the dictionary indicating at least one quantitative parameter in the subject.
