Quick Overview
Artifact Information
NAME
Quadrupole artifact
DESCRIPTION
Signal loss, intensity variations
REASON
B1 disturbance
HELP
STIR
Fat suppression (SPIR or FatSat) is very critical to the magnetic field homogeneity. Eddy currents in the patient results in B1 disturbance from left to right and from anterior to posterior. The artifact is seen as signal intensity variations with SPIR, like a signal intensity loss diagonal in the image. The short T1 inversion recovery (STIR) sequence is due to another type of fat suppression insensitive to this artifact.
mri safety guidance
Image Guidance
Take short T1 inversion recovery (STIR) instead spectral presaturation inversion recovery (SPIR) for fat suppression.
