The effect of homonuclear J modulation on 19F spin‐echo images is evidenced by a substantial reduction in signal when the echo time, TE, approaches 1 /2J, with a subsequent increase in signal at longer TEs. Suppression of the J‐modulation effect is demonstrated using chemical Shift‐Selective 180° refocusing pulses. © 1991 Academic Press, Inc.
