18. A computer readable media, comprising a non-transitory, computer-readable storage medium having computer-executable program instructions embodied therein for a method of preparing a parametric tissue map for tissue in a subject, comprising instructions for:
receiving Diffusion-weighted Magnetic Resonance Imaging (D-w MRI) acquisition data comprising a diffusion-weighted 1H2O signal;
determining a b-space decay of one or more voxels in the D-w MRI acquisition data, wherein the b-space decay is a decay of log(S/S0) relative to b, S is a signal intensity of the diffusion-weighted 1H2O signal, S0 is a signal intensity of the diffusion-weighted 1H2O signal immediately after coherence creation, and b is a normalized coherence decay measure; and
selecting a simulated decay of the diffusion-weighted 1H2O signal in b-space from an electronic library of simulated decays of the diffusion-weighted 1H2O signal in b-space that matches the b-space decay of the one or more voxels in the D-w MRI acquisition data, thereby preparing one or more parametric tissue maps of the D-w MRI acquisition data.
