fat suppression

An MRI term for the process of utilising specific parameters (e.g., STIR (short TI inversion recovery) sequences) to remove the noise caused by fat from the images.

fat suppression

In magnetic resonance imaging, the dampening of bright signals given off by body fat to allow other tissues to become more visible.
