What would happen if you have metal in an MRI?
The presence of metal can be a serious problem in MRI, because (1) Magnetic metals can experience a force in the scanner, (2) Long wires (such as in pacemakers) can result in induced currents and heating from the RF magnetic field and (3) Metals cause the static (B0) magnetic field to be inhomogeneous, causing severe …
Can you get an MRI if you have hardware in your body?
In general, metallic orthopedic implants are not affected by MRI. Your implant or device may come with a special information card that you should bring to your appointment and show to the technologist. Some implants are not compatible with MRI scanners.

Can you have an MRI if you have stainless steel in your body?
Projectile or missile effect: Ferrous-based materials, nickel alloys and most stainless steel materials are not compatible with the MRI environment. When these materials are exposed to a strong magnetic field, they can be pulled violently toward the magnetic source.
Can you have an MRI with metal in your back?
Patients who have had metallic devices placed in their back (such as pedicle screws or anterior interbody cages) can have an MRI scan, but the resolution of the scan is often severely hampered by the metal device and the spine is not well imaged.
