FATSAT is used to minimise the signal from fat, relative to surrounding tissues. In
musculoskeletal applications it is used to minimise the fat signal in the marrow emphasising the signal from marrow oedema (due to bone contusion, tumour, infection etc.). When used for the eye orbits it suppresses the retro-orbital fat to allow detection of an enhancing etro-orbital pathology on a contrast-enhanced study. FATSAT applied to the neck suppresses fat in order to detect and better evaluate the extent of a mass. FATSAT is
actually used in many other clinical applications, such as body MRI (liver, kidney imaging)
and breast MRI to name a few examples.
