As shown in Fig. , the PEGDA hydrogel exhibited a fast particle exchange at the beginning of the analysis, potentially from the water particles surrounding the scaffold on their immediate surface. Yet, the water contained in the core of the scaffold took a longer time to diffuse. The system appeared to reach equilibrium distribution 2 and 40 minutes into the experiment. However, the scaffold ROI retained the highest 1 H signal intensity (Fig. ). On the other hand, the CMC cryogel showed a more uniform diffusion for its enclosed water, with the system stabilising after 1 hour and 20 minutes, as shown in Fig. . Furthermore, the pixel intensities in the 1 H images (Fig. ) were more uniformly distributed by the end of the experiment, suggesting complete diffusion of all the water contained in the scaffold. Hence, with these experiments, we showed the usefulness of MRI to characterise inherent properties of bio-materials (i.e. diffusion characteristics) with a high enough resolution to determine differences between scaffolds types.
