Spatial SAT Level

Use the Spatial SAT Level User CV with 2D MERGE to vary the amount of tissue suppression for spatial SAT pulses.

There are three options for 2D MERGE:

  • 0 = Light
  • 1 = Medium (Recommended)
  • 2 = Strong

To acquire the previous or legacy SAT value, type in the following in the PSD Name text field on the PSD/Imaging Options screen: 2dmerge_classic.

Considerations

  • Spatial SAT 1 or 2 may reduce the number of available slices per TR. Consider selecting Auto TR from the TR menu on the Scan parameters screen to optimize the TR for a single acquisition.
  • Spatial SAT 1 or 2 may result in reduced signal suppression in areas where the SAT pulses overlap. Therefore, is it recommended that you don't overlap SAT pulses.
