Before you receive an MRI, a technician will ask you to remove any metal items you are wearing, such as jewelry, glasses or belt buckles. You should tell her about any medical implants you have. The MRI machine's powerful magnetic field attracts ferrous, or iron-containing, metals and can cause serious injury. Even in the absence of injury, metal objects can distort the MRI image and make it difficult to read. Safety experts have cleared some metals for use during MRIs. Orthopedic surgeons favor titanium implants for their strength and compatibility with body tissues.

Magnetic resonance imaging MRI is widely used for the diagnosis, staging, and follow-up of diseases. MRI is a very useful diagnostic tool for musculoskeletal and cerebrovascular imaging, because it has excellent soft tissue contrast and is considered to be safer than other modalities, as it does not expose the body to radiation [ 1 ]. However, MRI is not without risks. Developments in medicine have led to the use of various implants, such as dental and orthopedic implants, in our bodies [ 2 ]. In the field of craniofacial surgery, the use of titanium plates and screws in open reduction and internal fixation procedures has exploded since the late 20th century, and titanium is now considered to be the material of choice for implants. Titanium plates are frequently used for cranioplasty, reconstruction of the facial bones, and reconstruction of the orbital bone, because they yield excellent results without posing any major problems in terms of biosafety [ 3 ].

Because we are using a large magnet, we have to take a very close look at any metal objects that need to enter the scan room. Even small objects such as an ink pen need to be evaluated before entering the scan room. MR safe is defined as any object, device, implant, or equipment that poses no known hazards in the MRI environment. Our equipment in the scan rooms will have a green sticker on them that clearly state that it is safe to be in the scan room.
