A new echo‐time‐encoded chemical‐shift imaging technique applicable to dual‐peak spectroscopic imaging with large magnetic field inhomogeneity is proposed and studied. The basic concept and its applications to modest field homogeneity (⋍3.0 ppm) as well as to relatively large field inhomogeneity (⋍10.5 ppm) are discussed. Actual pulse sequences are given and some experimental results on human volunteers obtained with a 2.0‐T KAIS NMR system are also presented. © 1987 Academic Press, Inc.
