Magnetic resonance current density imaging of chemical processes and reactions

Electric current density imaging was used to image conductivity changes tha t occur as a chemical process or reaction progresses. Feasibility was asses sed in two models representing the dissolving of an ionic solid and the for mation of an insoluble precipitate. In both models, temporal and spatial ch anges in ionic concentrations were obtained on current density images. As e xpected, the images showed significant signal enhancement along the ionizat ion/dissociation sites. (C) 1999 Academic Press.
