The present invention provides a magnetic resonance temperature imaging method and apparatus, and relates to the field of magnetic resonance. According to the magnetic resonance temperature imaging method and apparatus, accuracy and precision of a water-fat tissue temperature image at a current moment are improved by using a two-step iterative temperature estimation algorithm, a magnetic resonance signal model includes multiple fat peaks, and a fourth strength amplitude value of a water signal, a fourth strength amplitude value of a fat signal, a fourth field drift caused by a non-uniform main magnetic field, and the water-fat tissue temperature image at the current moment that minimize a difference between signal strength and signal strength before fitting are estimated. |
