FIG. 5.

The left column shows the absorption mode spectra (water peak only) from voxel 1 shown in Fig. 4. (a) FT and (b) SLIM spatial reconstructions of the phase-encoded data show distortions of the spectrum. (c) NL-CSI reconstruction leads to removal of this distortion, as shown by improvement of the lineshape, and agrees with the (d) PRESS-acquired spectrum. In the right column the scale is expanded to show the metabolite peaks in the spectrum: (e) FT, (f) SLIM, (g) NL-CSI, and (h) PRESS. NL-CSI reconstruction show significantly improved lineshape over FT and SLIM reconstructions.
