FIG. 5.

KESA B₀ maps (a,b) and alternating-TE B₀ maps (c,d) at two different time points of runs 3 (a,c) and 4 (b,d). e: Corresponding B₀ time courses in a representative pixel (crosshair in a). The slice is the same as in Fig. 4 and the left images in b,d correspond to the same time point as in Fig. 4. The global B₀ offsets determined from the automatic residual deblurring have been added to the KESA B₀ maps.
