Diagram of the effect of temperature (T) on the fat-water frequency shift. At body temperature, 37°C, the fat-water frequency shift in phantoms is approximately 3.35 ppm21. As the temperature lowers, due to the temperature dependence of the water resonance peak and the temperature independence of the fat resonance peaks, the fat-water frequency shift increases at a rate of approximately 0.01 ppm/°C15,17. Note that the relative amplitudes and frequencies of the fat peaks are assumed to be constant with changes in temperature.
