If you have metal or electronic devices in your body such as artificial joints or heart valves, a pacemaker or rods, plates or screws holding bones in place, be sure to tell the technician. Metal may interfere with the magnetic field used to create an MRI image and can cause a safety hazard.Will I be able to have an MRI? Yes. There is no reason why you cannot have an MRI. It is true the rods will interfere with the image on the MRI to some extent, but new techniques allow for visualization of the spine particularly adjacent to the instrumentation.Metal that is well secured to the bone, such as hip and knee joint replacements, will not be affected by an MRI. The metal won’t heat up or move in response to the machine. But if the metal is near an organ, such as the prostate, distortion could be a problem.

Can you have MRI with titanium rods?
Titanium is a paramagnetic material that is not affected by the magnetic field of MRI. The risk of implant-based complications is very low, and MRI can be safely used in patients with implants. The titanium plates used in the craniofacial area, however, are made of alloys.
Can someone with a metal implant have an MRI?
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.

Is there an alternative to an MRI scan?
A CT scan may be recommended if a patient can’t have an MRI. People with metal implants, pacemakers or other implanted devices shouldn’t have an MRI due to the powerful magnet inside the machine. CT scans create images of bones and soft tissues.
Are stainless steel implants MRI safe?
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 a back fusion?
Indeed, other studies assessing imaging following posterior lumbar interbody fusion (PLIF) have suggested that although fusion can be evaluated using MRI scan and CT scan by the 12-month mark, further progress toward complete union can take up to 24 months or longer.
Are titanium rods magnetic?
If you’re having a hip replacement you might be wondering if titanium is magnetic. It turns out that titanium is weakly magnetic (compared to other ferromagnetic materials) in the presence of an externally applied magnetic field. Titanium also exhibts the Lenz Effect but to a lesser extent that many other metals.

Why is metal bad for 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 …
What happens if you wear a ring during an MRI?

- Maybe Limit Your Bathroom Trips.
- Always Listen to Your Preparation Instructions.
- Do NOT Keep Metal on Your Body.
- Tell the Technicians About Any Pre-Existing Conditions.

What if I can’t get my rings off for an MRI?
Use a lubricant such as soap and water, oil, or Windex. Yes Windex! The surfactants help to reduce the surface tension between the ring and the skin, making the ring easier to maneuver off of the finger. Also, Windex will not gum up your ring like other lubricants such as oil or lotion could.
What drug do they give you before an MRI?
Many patients find that an oral benzodiazepine, such as Xanax, Ativan, or Valium, taken prior to the exam sufficiently relieves their anxiety and allows them to complete an MRI with relative ease.
