The concept of temporal echo multiplexing is defined and used to develop rapid bipha‐sic spin‐echo sequences for imaging the heart. Three imaging sequences, based on four‐echo and two‐echo multiplexing and rapid single echo (i.e., conventional spin‐echo imaging), are compared. Preliminary results indicate that two‐echo multiplexing yields a significantly reduced acquisition time window with image quality that is only slightly inferior to single‐echo imaging. Single‐echo biphasic imaging results in the most consistent image quality. © 1989 Academic press, Inc.
