Enhanced fat suppression

Enhanced fat suppression is only available for DWI scans. It is a water excitation technique to further reduce fat signal. It makes a DWI protocol with IR Prepared Imaging Option, SPECIAL, or Chemical fat SAT more robust. For IR Prepared and SPECIAL, when the User CV is on, the scan is less sensitive to the TI Time selected from the Details scan page. The settings for the User CV include the following:

• Enhanced fat suppression = 0 (off and the default setting). This option is only available when IR Prepared (from the Imaging Option screen), Special or Fat (from the Chem SAT menu) are selected.
• Enhanced fat suppression = 1 (on) is available for scans on these systems:
  • 1.5T
