Can I Have an MRI With Metal Implants?

If you have a metal implant and need an MRI, the short answer is reassuring: most people with metal implants can safely have an MRI. Modern implants are usually made from MRI-compatible materials, and our team reviews every device before your scan. That said, some implants are not safe in the magnetic field, and a few need special settings — so the honest answer is it depends on the specific implant.

Because an MRI uses a very strong magnet, safety screening is the single most important step before any scan. Here is what is generally safe, what needs review, and exactly what to tell us before you come in.

Why Metal Matters in an MRI

An MRI creates images using a powerful magnetic field — far stronger than a common refrigerator magnet. That magnet can pull on, heat, or interfere with certain metal objects and electronic devices inside the body. This is why every patient completes a safety questionnaire, and why you should never assume an implant is fine without telling the technologist. Screening exists precisely so we can catch the small number of implants that are not compatible.

Implants That Are Usually MRI-Safe

Many common orthopedic and surgical implants are made from titanium or other non-magnetic materials and are typically safe to scan, especially once they have been in place for several weeks:

• Joint replacements (hip, knee, shoulder)
• Orthopedic screws, plates, rods, and pins
• Dental fillings, crowns, and most dental implants
• Sternal wires after heart surgery
• Most modern heart stents and vascular stents
• IUDs (copper and hormonal)

Even when these are safe, metal near the scan area can sometimes cause a small distortion in the image. Our radiologists know how to adjust for this, and it rarely affects the diagnosis.

Implants That Need Review Before Scanning

Some devices are not automatically unsafe, but they must be checked and cleared first — and sometimes require a specific "MR-conditional" setting:

• Pacemakers and defibrillators (ICDs) — many newer models are MR-conditional and can be scanned with special preparation, but older ones may not be.
• Cochlear implants and some hearing devices
• Programmable shunts (for hydrocephalus)
• Neurostimulators and pain pumps
• Aneurysm clips — the material matters greatly here
• Drug-infusion pumps

For any of these, bring the device's ID card or the make and model if you have it. That lets us confirm the exact MRI safety rating before your appointment.

Implants That May Not Be MRI-Compatible

A small number of items can make an MRI unsafe, including certain older aneurysm clips, some older implanted devices, and metal fragments in the eye (a real concern for people who have done metalworking or welding). If there is any question about a metal fragment near the eyes, we may order a quick X-ray to check first. When an MRI is not an option, a CT scan can often provide the answer instead.

What to Tell Us Before Your MRI

When you schedule your MRI and again at check-in, tell us about any of the following — even if you think it is minor:

• Any surgery that left screws, plates, joints, stents, or clips
• A pacemaker, defibrillator, or any implanted electronic device
• A cochlear implant, neurostimulator, or medication pump
• A history of metal in the eye (welding, grinding, machining)
• Shrapnel, bullets, or other embedded metal fragments
• Tattoos or permanent makeup (rarely an issue, but worth mentioning)

This is the same safety screening every patient completes. When in doubt, mention it — it is always better for us to review and clear an implant than to skip it.

Do I Need a Referral to Ask About This?

No. In Florida, self-pay patients can get an MRI without an outside referral — and our physician and technologists handle the implant safety review as part of that same process. So even if you are booking directly, your implant will be screened and cleared before you are scanned. Screening is never skipped for self-pay patients.

The Bottom Line

Most metal implants — joint replacements, orthopedic hardware, dental work, and many stents — are safe for an MRI, while devices like pacemakers, cochlear implants, and aneurysm clips need to be reviewed and cleared first. The key is simple: tell us about every implant or device before your scan. If an MRI is not safe for you, we will recommend a safe alternative such as a CT scan or open MRI.
