✦ Synopsis

Abstract

We describe the speeding up of snapshot FLASH MRI by placing a slice selection experiment before the whole imaging sequence. In conventional snapshot FLASH slice selection is made in every projection, thus consuming a great deal of experimental time. This problem can be overcome by applying only one slice‐selective procedure before starting the imaging. The idea is to make a selective saturation of the outer volume and to interrogate the unaffected slice by a train of rapid, hard, low‐angle pulses. By this new method the measuring times of snapshot FLASH can be further reduced. © 1992 Academic Press, Inc.
