WebFat saturation or suppression is based on the Larmor equation that magnetic dipoles precess around the direction of an applied magnetic field. The frequency of the precession is directly proportional to the magnet field strength ƒ 0 = ƔB 0, where ƒ 0 is the precession frequency, B 0 0) at 1.5T, the resonance frequency of 1H would be (42.58 MHz/T) x (1.5T) … WebMRI Fat Saturation (Fat Sat, CHESS, SPIR, SPECIAL) In the triglyceride molecules of fat, the electronic environment (shield) of the protons is not the same as that of water molecules. The 2 kinds of molecules have different proton resonance frequencies, measured by chemical shift (3.5 ppm).
