Spectral-Spatial FatSAT

Spectral-Spatial FatSAT is designed to reduce annefact artifact on 3.0T systems with the following scan parameters:

• fMRI scan: Echo Planar Imaging family, Gradient Echo EPI pulse, fMRI or Multi-Phase Imaging Option.
• Fat selected from the Chem Sat menu on the Scan Parameter screen.

Standard Fat SAT uses a non-selective fat saturation pulse, which can result in signal outside of the imaging area being aliased into the image. Spectral-Spatial Fat SAT applies a spatial-spectral fat SAT pulse that minimizes this issue and improves signal stability. The settings for the User CV include the following:

• Spectral-Spatial FatSAT = 0 (off) applies the standard fat saturation pulse.
• Spectral-Spatial FatSAT = 1 (on) applies the spectral-spatial fat saturation pulse.
