ULTRAFAST LOW-ANGLE RARE - U-FLARE

The subsecond application of the RARE technique is described. Two possible methods of implementation are discussed, one in which T2 contrast is manipulated by temporal reordering of the phase‐encoding gradient, and the other in which the phase‐encoding order is held constant and the contrast is manipulated by means of a spin‐echo preparation experiment. In vivo images obtained with the latter method are presented and applications of the sequence discussed. © 1991 Academic Press, Inc. Copyright © 1991 Wiley‐Liss, Inc., A Wiley Company
