Total Choline

Shimming in Neuro-applications

  • Regular scanner shimming with 2nd order shimming

  • 16-ch Elara neuro-shim coils driven with Jupiter shim amplifiers

  • Total Choline metabolite maps show higher concentrations in white matter

Improvements

  • Reduced frequency shift in the frontal cortex

  • More homogeneous magnetic field

  • Better white/gray matter delineation in total Choline

  • Recovered voxels that previously could not be fit
