Spin echo imaging of multiple chemical shifts.
A method to obtain separate cross-sectional NMR images of chemically different species on the basis of their difference in chemical shift is presented. The total experiment time is no longer than that required for a conventional image and the method retains the full sensitivity of a spin-echo 2DFT imaging experiment. Simple addition of the chemical-shift selective images produces an image free from chemical-shift artifacts. Results of an in vivo experiment on a human subject are presented.
