  • Method for fat suppression in magnetic resonance imaging
    Patent number: 5250899
    Abstract: A method for suppressing fat in a magnetic resonance image of a target organ, wherein fat is present in the vicinity of the target organ involves subjecting the target organ to electromagnetic energy so as to cause an organ signal response and a fat signal response related to the magnetization of the organ and the fat, respectively. The subjecting to electromagnetic energy involves subjecting the target organ to a saturation preamble and thereafter subjecting the target organ to an offsetting spin-echo sequence. The organ and fat responses are detected and image information based on the responses is generated. The saturation preamble, selectively excites and then dephases a particular substance, such as fat, in the vicinity of the target organ. Preferably exciting and then dephasing involves subjecting the target organ to a Hore 1-3-3-1 signal.
