Abstract

We describe several applications of a versatile pulse sequence family employing multiple spin echoes within one acquisition to accelerate multidimensional experiments. The core sequence, called multiple modulation multiple echo, measures the maximal set of spin echoes generated from a set of RF pulses with unequal time spacings. These echoes can be modulated individually to exhibit different encoding. As a result, one scan of the sequence determines a series of data points as a function of the specific encoding mechanism. The variety of realizations of this sequence includes single shot measurements of diffusion or flow in 1D, 2D, and single‐scan 2D slice‐selective imaging. The essential spin dynamics of such sequences is introduced and their applications are reviewed. Β© 2007 Wiley Periodicals, Inc. Concepts Magn Reson Part A 30A: 358–377, 2007.

## Abstract We report a new type of SSFP imaging sequences for acquiring higher‐order echoes. Spins excited during a cycle have, in a sense, a phase memory such that they can be refocused several cycles down the line, and since the spins are pulsed under a steady‐state condition, the resulting echo
