Abstract

A new technique termed MRF-X is introduced that models two-compartment chemical exchange to generate a dictionary for subvoxel mapping of T1, T2, volume fraction, and exchange rate. Simulations indicate that the MRF-X model can map subvoxel parameters in cases where standard mapping sequences would map a single effective T1 or T2 value. MRF-X has the potential to directly measure properties of tissue microstructure.
