要旨

MR Fingerprinting (MRF) can simultaneously map multiple parameters and can be used to compute estimates of tissue fractions. However, MRF-derived M maps contain information about both proton density (PD) and the receiver sensitivity profile (RP). Here we estimate relative PD and RP from MRF M and T maps. Relative PD and tissue fractions are combined for absolute quantity mapping of CSF, gray matter, and white matter as a fraction of the voxel equilibrium magnetization.
