In this study, we demonstrated a nondestructive 3D monitoring method of polyethylene glycol (PEG) impregnation in wood using magnetic resonance imaging ultrashort echo time (UTE). The materials used were sound wood, which was impregnated with a 20 wt.% aqueous solution of PEG4000 for two weeks and further impregnated at an interval of two weeks with PEG concentrations of 40, 60, 80, and 100 wt.%, as well as archaeological wood impregnated with a 40 wt.% solution of PEG 4000 at room temperature for about 4 years. The signal intensity of the PEG4000 aqueous solution monotonically increased with increasing concentration of PEG, although under certain temperature conditions. Stereoscopic images were created from the UTE image data of the wood sample, and it was possible to represent the PEG-impregnated portion of the wood sample in 3D. In conclusion, it has been suggested that UTE imaging is a feasible method to nondestructively visualize the PEG impregnation state of waterlogged wood in 3D and to evaluate and monitor it from all directions with a high spatial resolution, under specific temperature control of the material
