In MRI of the liver, prescan adjustments are often performed prior to running each pulse sequence. However, repeating adjustments lengthens scan time, and adjustment data can, in many cases, be carried forward from pulse sequence to pulse sequence. Minimizing prescan adjustments (especially repeated shimming) by fixing table position and allowing maximal adjustment tolerances can reduce total examination time without reducing image quality or the quality of quantitative MRI data.
