Abstract

We measure the velocity distribution of slow fluid flow in model systems using stimulated echoes and velocity phase encoding. We show velocity images of slow coherent flow with velocities of the order of 0.1 mm/s which is slower than can be obtained by the bolus‐tracking method. The eddy current errors were compensated by phase Correction. © 1990 Academic Press, Inc.

In this paper we present a pulse sequence that combines a displacement-encoded stimulated echo with rapid sampling of k-space by means of turbo spin echo imaging. The stimulated echo enables the use of long observation times between the two pulsed field gradients that sample q-space completely. Prop

This transverse magnetization can be used to measure a spin echo, in addition to the stimulated echo. Two-dimensional single-
