## Abstract MRI and swelling experiments are used to probe the state of water and infer the microstructure of chitosan hydrogels. SEM reveals a porous open scaffoldโ€type structure for hydrogels that were equilibrated at 2โ€‰ยฐC before freezing as compared to those equilibrated at 37โ€‰ยฐC. ADC MRI measur
