Abstract
A system and method for performing magnetic resonance fingerprinting (MRF) is provided that includes performing a pulse sequence that is sensitive to field inhomogeneities to acquire a series of signal evolutions form a region of interest (ROI) of the subject to form MRF data. The method also includes varying field inhomogeneities across the ROI to acquire the series of signal evolutions, comparing the MRF data with an MRF dictionary to determine at least one tissue property of the subject in the ROI, and producing at least one map of the at least one tissue property.
