Double‐inversion fast spin‐echo (FSE) pulse sequences can be designed to provide excellent suppression of blood signal in black‐blood MRI. However, because a nonselective inversion is used, these sequences typically have been highly inefficient. In this work it is demonstrated that the efficiency of double‐inversion sequences can be greatly improved by a form of interleaving in which all of the slices to be imaged in a single pass are reinverted each time a signal is obtained from any single slice. To date, several studies have demonstrated a high level of blood suppression with these more efficient techniques. Magn Reson Med 47:1017– 1021, 2002. © 2002 Wiley‐Liss, Inc.
