## Abstract The fast spin echo sequence combines data from many echo signals in a CarrβPurcellβMeiboomβGill echo train to form a single image. Much of the signal in the second and later echoes results from the coherent addition of stimulated echo signal components back to the spin echo signal. Beca

A closed matrix form solution of the Bloch-Torrey equation is presented for the magnetization density of spins diffusing in a bounded region under a steady gradient field and for the Stejskal-Tanner gradient pulse sequence, assuming straightforward generalization to any step-wise gradient profile.

## Abstract We propose a novel application of double pulsed gradient spinβecho NMR in which two pairs of gradient pulses are used successively to encode the spin magnetization. These pairs were applied with gradient directions collinear and orthogonal, and the results were compared. The method can
