FGATIR
Sharp gray/white matter contrast, with no extra sequence to schedule.
Fast Gray Matter Acquisition T1 Inversion Recovery (FGATIR) sharpens the boundary between gray and white matter in deep brain structures — synthesized from STAGE's T1 and proton-density maps rather than a separate inversion-recovery scan.
COMPUTED CONTRAST
Computed, not scanned separately.
FGATIR is computed from STAGE's co-registered T1 and proton-density maps, sharpening the white-matter borders that routine T1-weighted series blur — without adding scan time or a separate inversion-recovery protocol to plan around.
CLINICAL FIT
Where FGATIR shows up in the applications
STAGE for DBS
FGATIR's gray/white matter separation helps delineate the STN, GPi and other subcortical targets — the contrast planning teams lean on most, paired with iron-sensitive QSM.
