Nonwatersuppressed MRSI (magnetic resonance spectroscopy imaging) offers a number of advantages; however, spectra are hampered by the sideband artifacts. The origin of those is associated with the vibration of the gradient coils, and most of the sidebands are assumed to be related to the crusher gradients.

RARE University of Warwick

Another feature common to RARE (and many other spin echo sequences) are the gradient 'lobes' on either side of the π pulse selective gradients. These are known as crusher gradients, and act to dephase spurious signal coming from outside the slice of interest.
