Combination of Time‐Dependent Self‐Diffusion Measurements (Dynamic Imaging) with Magnetic Resonance Imaging

The new NMR method, demonstrated in the present work, allows within local small volumes the determination of integral structural parameters like the surface‐to‐pore volume ratio or the tortuosity of a fluid‐filled porous medium. A combination of conventional imaging (MRI) with measurements of observation‐time dependent self‐diffusion (dynamic imaging) was used.
