FIGURE 4.
Comparison of 2D GESE EPTI results reconstructed by B 0‐informed GRAPPA and subspace reconstruction for a 9‐shot 2D EPTI acquisition. The images at four selected TEs (out of 120 TEs) are shown, where images at the early and late TEs show severe artifacts from the GRAPPA reconstruction, but the subspace method provided clean images. The signal drops of GRAPPA at the edge echoes are also shown in the signal curve. In contrast, subspace reconstruction obtained accurate signal evolution without signal drop or large fluctuation
