|a High-resolution NMR images on three different present-day wood samples and an archaeological wood specimen were presented and discussed. Although the spatial resolution is still low to perform dendrology for the exact identification of the wooden species, the T2 -spin-density weighted images exhibit contrasts that are in excellent agreement with optical histological images. On the other hand, T2 * and T1 -weighted images provide physiological information that is not obtainable by the usual light microscopic investigations. Moreover, the diffusion-weighted images show the anisotropic behaviour of the water diffusion coefficient quantified along and perpendicularly to vascular bundles (vessels and tracheids), which can be related to the morphology and size of wooden microstructure. This work suggests that high-resolution multiparametric MRI may be a useful tool to increase the information obtainable from the waterlogged archaeological wood remains in a completely non-invasive and non-destructive approach. Therefore, it would be desirable to further develop the hardware and functional characteristics of MRI scanners to improve their potential application in the field of wooden cultural heritage
