In this work, we present an optimized 3D technique that can simultaneously acquire quantitative 1H density, T1, T2, B1+ maps and a 23Na image of the whole head in a reasonable scan time (~20 min).
Figure 4: In-vivo results. Sodium images are shown in the first row, which has 3 mm3 isotropic resolution. Proton T1,T2, B1+ maps from the three directions are shown beneath the sodium images.
Figure 1: Sequence diagram of the 3D simultaneous technique. The bars on top show the sodium excitations with constant flip angle and the proton MRF train with various flip angles. The details of the sequence for different segments are shown in the corresponding cards on the bottom.
