Our aim was to evaluate metal artifacts induced by biodegradable magnesium alloys a new class of degradable biomaterials - at CT and MR imaging at 1.5T in comparison to standard titanium and stainless steel controls. It was shown that biodegradable magnesium alloys show less metal induced artifacts at CT and MR imaging than the controls.
