Tb. Benson et Pj. Mcdonald, PROFILE AMPLITUDE-MODULATION IN STRAY-FIELD MAGNETIC-RESONANCE-IMAGING, Journal of magnetic resonance. Series A, 112(1), 1995, pp. 17-23
It is shown that the amplitudes of successive echoes in a stray-field
magnetic resonance imaging (STRAFI) experiment are strongly modulated
by the intense magnetic-field gradient used and by sample movement dur
ing the experiment. In this paper the modulation is analyzed so that q
uantitative interpretation of STRAFI images reconstructed from multipl
e-echo data can be made. Spin-spin relaxation is included. Theoretical
predictions of relative echo intensities are compared with data obtai
ned from an experiment to visualize acetone penetration into PVC. (C)
