Magnesium (Mg) and itsbiodegradable alloys are promising biomaterialsfor bone application. However, their corrosionbehaviour is still poorly understood and theresorption mechanism is still unpredictable in vivo,due to the high complexity of the physiologicalenvironment [1]. Here we report on the in vivodegradation process of 3 Mg alloys as observed onsynchrotron-based micro computed tomography(SRµCT) and on corresponding histologicalsections. SRµCT, thanks to the high contrast-tonoiseratio, enables to clearly detect the changesthat the Mg alloys undergo during corrosion, in anon-destructive way and directly in the bone [2]
