Which is the best strategy to improve shimming at high
fields? This educational presentation aims to review and
compare different shimming techniques based on few
simple experiments on phantoms and human volunteers.
Beside the well established automatic procedures,

shimming at high fields to achieve better full width at
half maximum (FWHM) of the spectral lineshape. But this
time consuming approach requires mastering the Ancient
and Honourable Art of Shimming.
