Abstract:
A method of resolving images of a first chemical species X and a second chemical species Y in an imaged multi-voxel body, comprising:acquiring three complex magnetic resonance images of the body, wherein the first and second chemical species have relative phase shifts of .alpha..sub.0, .alpha..sub.0 +.alpha., and .alpha..sub.0 +2.alpha., respectively, and exp(i.DELTA..omega..tau..sub.0)exp(i.DELTA..omega..tau.).noteq..+-.1, where .DELTA..omega. is a difference in Larmor frequencies between the two species X and Y, .tau..sub.0 =.alpha..sub.0 /.DELTA..omega., and .tau.=.alpha./.DELTA..omega.;combining the three complex images to obtain two solution sets for X and Y;selecting one solution set for X and Y based on a known relative difference in Larmor frequencies of X and Y; andoutputting two separate images of the chemical species X and Y.
