fat saturation

fat saturation

A specialised MRI technique which selectively saturates fat protons before acquiring data, as in standard sequences, to reduce fat signal. The pre-saturation pulse is applied before each slice selection. Fat saturation requires a homogeneous magnetic field and precise frequency calibration.

MRIs were performed at baseline and 12 weeks using three different sequences: T1-weighted turbospin-echo (TSE) sequences to assess chronic lesions; fat-saturated short tau inversion recovery (STIR) sequences and TSE sequences after application of gadolinium (gad)-DTPA with fat saturation to determine disease activity.
