In this work, we present a 3D
sequence that can simultaneously capture quantitative 1H density, T1, T2, B1+
maps and a 23Na image of the whole head in a reasonable scan time (~10 min).
The gradient momenta are strategically
distributed to simultaneously acquire a full-radial trajectory for proton and a
center-out radial trajectory for sodium in one single readout. A sodium SNR
comparison, verification of the proton multi-parametric maps, and in-vivo
results are shown.
