2 Safety
Localization errors due to
distortion
Potato chip artifact
DIXON swapping

 CAUTION
Incorrect localization data due to spatial non-linearity of the
gradient field and inhomogeneity of the static magnetic field!
Incorrect diagnosis
◆ Take localization errors into account while planning
interventions or biopsies.
 CAUTION
Distorted slice edges in the margin due to spatial non-linearity of
the gradient field and inhomogeneity of the static magnetic
field!
Incorrect diagnosis
◆ Take into account slice distortion at the margins of the MR
image. This applies in particular to graphic slice positioning
(GSP) as well as other graphic slice displays and slice
positioning data independent of the possible use of distortion
correction.
 WARNING
When using the DIXON method, water and fat swaps might
occur!
Incorrect diagnosis
◆ Diagnosis should be confirmed by a second contrast and/or a
different orientation.
