ABSTRACT

Nuclear magnetic resonance imaging and magnetic resonance determinations of flow and diffusion are increasingly coming to the fore as powerful means for characterizing dynamic processes in diverse areas of materials science covering physics, chemistry, biology and engineering. In this chapter, the basic concepts of the methods are introduced and a few selected examples presented to show the power of the techniques. Although flow and diffusion through bulk samples can be measured, they are primarily treated here as parameters to be mapped in an imaging experiment. To that end, imaging is dealt with first, followed by flow and diffusion, along with other contrast parameters such as spin-relaxation times and chemical shift.
