Chemical shift imaging (CSI) often suffers from the inconvenient shape of its spatial
response function (SRF), which affects both localization and signal-to-noise ratio. Replacing
the magnetic field gradients for phase encoding by higher order magnetic fields allows a
better adjustment of the SRF to the structures in the sample. We combined this principle with
the SLOOP (spectral localization with optimal pointspread function) technique to
simultaneously obtain spectra from several arbitrarily shaped compartments within a …
