FLASH(SPGR/T1-FFE/RF Spoiled SARGE/RSSG/FAstFE/S Tage/T1-FAST) Fat Sat
MRI image appearance
The easiest way to identify T1 FLASH fat-saturated images is to look for adipose tissues in the body, such as subcutaneous fat and fat in the bone marrow. Areas containing adipose tissues appear dark on T1 FLASH fat-saturated images. All other characteristics of the T1 VIBE fat-saturated images remain the same as the T1 FLASH images.

Pathological appearance
Pathologies containing adipose tissue will manifest as areas of darkness on T1 FLASH fat-saturated images (for instance, lipomas). All remaining pathologies will exhibit a comparable appearance to standard T1-weighted images.
