The feasibility of simultaneous MWF/QSM mapping is demonstrated
by using the multi-echo gradient echo (mGRE) sequence in this study.
The retrospective and the perspective undersampling experiments have shown the
potential of obtaining whole brain QSM/MWF
quantifications in 1 minute.

4. The MWF/QSM maps of 8
adjacent slices from one prospectively undersampled datasets with R=6 and the
fully-sampled dataset.
Figure 3. The profile plots corresponding to the black lines in
the QSM maps of the fully-sampled data and the TDLLS reconstructed data from 9
subjects (R=6). The blue lines and green lines in the plots refer to the signal
variations of the fully-sampled data and the TDLLS reconstructed data,
respectively. High agreements are observed
between the signal of TDLLS reconstructed data and that of the fully-sampled
data.
