The bone screw is machined from titanium ti 6al 4v-eli (astm f136 standard specification for wrought titanium-6aluminum-4vanadium eli (extra low interstitial) alloy for surgical implant applications) which is commonly used for implants such as plate/screws for bone fixation.Titanium is non-magnetic therefore, the risk of any ci or mri interference is minimal.Titanium is generally considered safe and compatible with mri and does not interfere significantly with the magnetic field of the mri.In addition, the size of the bone screw that was left in place is approximately 3mm in length with a 1mm diameter.
