Figure 1.

Time diagram of the proposed pulse sequence with interleaved acquisition of the MRSI and fMRI data. The MRSI data are acquired in modified EPSI trajectories while the fMRI data are acquired in EVI trajectories. In the MRSI acquisition, blipped gradients (shown in red) are applied in selected TRs to extend the k-space coverage (see Fig. 2). No water or lipid suppression is applied; in our current implementation, TE = 1.6 ms, TR = 160 ms, N₁ = 15, N₂ = 8, and ${\text{N}}_2^{\text{’}}=2$.
