Abstract

A fast multi‐section MR imaging technique is described. Gradient‐ and spin‐echo (GRASE) imaging utilizes the speed advantages of gradient refocusing while overcoming the image artifacts arising from static field inhomogeneity and chemical shift. Image contrast is determined by the T2 contrast in the Hahn spin echoes. A novel k‐space trajectory temporally modulates signals and demodulates artifacts. © 1991 Academic Press, Inc.
