Abstract:
1. A computer-implemented method for concurrently estimating an amount of fat and iron in anatomical tissue from magnetic resonance (MR) signal data, the method comprising: receiving a test signal representative of the anatomical tissue acquired using a MR pulse sequence type; generating a repository of reference signal data comprising a plurality of reference signals derived by an MR signal simulation for a plurality of different transverse relaxation rates, a plurality of different fat fractions, and the MR pulse sequence type; identifying a first reference signal in the plurality of reference signals, the first reference signal providing a best match to the test signal based on one or more matching criteria; searching the repository to determine a first transverse relaxation rate and a first fat fraction associated with the first reference signal; and estimating the amount of fat and iron in the anatomical tissue based on the first transverse relaxation rate and the first fat fraction.
