With the aim of assessing bone microarchitecture, several studies have intended to use MRI but the issue of air bubbles artefacts has been very scarcely reported. In the present study, we assessed air bubbles-related artefacts in MR images of human bone samples and intended to design a protocol to eliminate them. The method was validated using TSE MRI at 3T and high-resolution X-ray micro tomography. Morphological parameters computed from MRI recorded with and without the air bubbles artefacts were compared to those obtained from X-ray micro tomography.
