The article presents a discussion of the basic signal behavior of contrast‐modified RARE(TSE,FSE…)‐sequences which have been modified such that the echo train used for image encoding is preceded by a long echo interval in order to introduce the T 2 ‐contrast of conventional spin‐echo sequences while maintaining the high imaging speed of TSE. Sequences aimed at breathhold abdominal imaging as well as for the detection of hemorrhages in the CNS have been implemented and optimized. The significant difference in image contrast at identical echo times compared to unmodified TSE is demonstrated for different tissues. Magn Reson Med 43:577–582, 2000. © 2000 Wiley‐Liss, Inc.
