Getting an MRI scan can be an intimidating experience. You’re asked to remove all metal prior to the scan, including jewelry. But what if you forget and leave a ring on? Will it harm you or affect the results?
If you’re short on time, here’s a quick answer: wearing rings or other metal jewelry during an MRI is generally unsafe and can cause burns or distortions in the scan images. However, some establishments allow wedding bands.
In this comprehensive article, we’ll explain the MRI process, risks of wearing rings or metal in the scanner, exceptions for certain metals, and tips for preparing jewelry-wise before your appointment.
How an MRI Scanner Works
An MRI scanner is a medical device that uses powerful magnets and radio waves to create detailed images of the body’s internal structures. It is a non-invasive procedure that provides valuable information to doctors for diagnosing and monitoring various medical conditions.
Magnets and Radio Waves
The main components of an MRI scanner are the magnets and the radio wave transmitters and receivers. The magnets create a strong magnetic field around the patient’s body, aligning the protons in the body’s tissues.
When radio waves are transmitted into the body, the protons absorb the energy and then release it when the radio waves are turned off. The MRI machine detects these signals and uses them to create detailed images of the body.
The strength of the magnets used in an MRI scanner can vary, with higher field strengths generally providing more detailed images. The most common field strength is 1.5 Tesla, but some scanners can go up to 3 Tesla or even higher.
Why Metal is a Problem
Metal objects can be a problem during an MRI scan because they can be attracted to the strong magnetic field or interfere with the radio waves. This is why it is important to remove all metal objects before entering the MRI room, including jewelry, watches, and even clothing with metal zippers or buttons.
If a person wears a ring during an MRI scan, several things can happen. Firstly, the ring may become attracted to the magnet and be pulled towards it, potentially causing injury to the person wearing it.
Secondly, the metal in the ring can distort the magnetic field, affecting the quality of the images produced. Lastly, the metal in the ring can create artifacts on the images, making it difficult for the radiologist to interpret the results accurately.
It is essential for patients to inform their healthcare providers if they are wearing any metal objects before undergoing an MRI scan. In some cases, alternative imaging techniques may be recommended, or the patient may be asked to remove the metal object before proceeding with the scan.

Risks of Wearing Rings or Metal in an MRI
Burning, Heating, Discomfort
One of the main risks of wearing rings or any metal object during an MRI is the potential for burning, heating, and discomfort. The strong magnetic field generated by the MRI machine can interact with the metal in the ring, causing it to get hot.
This can lead to burns on the skin or even damage to the ring itself. The heating effect can be particularly dangerous if the metal is in close proximity to sensitive areas of the body, such as the fingers or hands.
It is important to remove all metal objects before entering the MRI room to avoid these risks.
Distortions and Artifacts in Images
Another risk of wearing rings or metal in an MRI is the potential for distortions and artifacts in the resulting images. The presence of metal can interfere with the magnetic field, causing distortions in the images and reducing their quality and accuracy.
This can make it more difficult for doctors to make an accurate diagnosis or evaluate the condition being examined. To ensure the best possible images, it is crucial to remove all metal objects before undergoing an MRI.
Projectile Risks
Wearing a ring or any other metal object during an MRI also poses a risk of projectiles. The strong magnetic field can attract and pull metal objects towards the machine, turning them into dangerous projectiles.
These projectiles can cause serious injuries to both the patient and the healthcare professionals present in the room. To prevent any accidents or injuries, it is absolutely necessary to remove all metal objects, including rings, before entering the MRI room.
Exceptions and Safe Metals
When it comes to wearing a ring during an MRI, there are a few exceptions and safe metals that can be considered. These metals include titanium, gold, silver, and platinum.
Titanium, Gold, Silver, Platinum
Titanium is a popular choice for jewelry because it is lightweight and hypoallergenic. It is also non-magnetic, which means it won’t be affected by the strong magnetic fields of an MRI machine. Gold, silver, and platinum are also safe metals to wear during an MRI.
These metals are non-ferrous, meaning they are not magnetic and won’t pose a risk during the procedure.
It’s important to note that the purity of these metals can vary, and it’s always a good idea to consult with a jewelry expert or your healthcare provider to ensure that the ring you’re wearing is made of a safe metal.
Why Some Metals are Safer
So why are some metals safer to wear during an MRI than others? The answer lies in their magnetic properties. MRI machines use powerful magnets to create detailed images of the body’s internal organs and tissues.
If a metal object, such as a ring, is worn during the procedure, it can be attracted to the magnetic field and potentially cause harm to the wearer.
Metals that are ferromagnetic, meaning they are strongly attracted to magnets, pose the greatest risk during an MRI. These metals include iron, nickel, and cobalt. Wearing a ring made of these metals during an MRI can lead to discomfort, movement of the ring, or even injury to the finger.
On the other hand, metals that are non-ferrous, like titanium, gold, silver, and platinum, are not attracted to magnets and are considered safe to wear during an MRI. These metals will not be affected by the magnetic field, allowing the procedure to be conducted without any complications.
It’s always best to err on the side of caution and remove any jewelry or metal objects before undergoing an MRI. However, if you’re unable to remove your ring, make sure it is made of a safe metal such as titanium, gold, silver, or platinum to minimize any potential risks.
Tips for Preparing Jewelry Before an MRI
Notify Technicians About Implants
Before undergoing an MRI, it is crucial to inform the technicians about any implants or medical devices you may have. This includes pacemakers, cochlear implants, or any other type of implant that could be affected by the magnetic fields generated by the MRI machine.
The technicians will provide you with the necessary instructions and precautions to ensure your safety during the procedure.
Remove All Magnetic Jewelry
It is essential to remove all magnetic jewelry before entering the MRI room. This includes rings, bracelets, necklaces, and earrings. Magnetic jewelry can interfere with the imaging process and potentially cause harm to you or damage to the MRI machine.
Therefore, it is best to leave all magnetic jewelry at home or in a safe place outside the MRI room.
Use Non-Metal Storage
To prevent any accidental mishaps, it is advisable to store your jewelry in a non-metal container or bag before entering the MRI room. This will ensure that your jewelry does not accidentally come into contact with the machine’s strong magnetic field.
Additionally, storing your jewelry separately will help you keep track of your belongings and avoid misplacing them during the procedure.
Remember, MRI machines use powerful magnets to generate detailed images of your body’s internal structures. It is crucial to follow these tips to ensure your safety and the smooth functioning of the MRI procedure.
If you have any concerns or questions, do not hesitate to discuss them with your healthcare provider or the MRI technician.
Conclusion
While most metal jewelry and rings need to be removed prior to an MRI, there are a few safer options that likely won’t cause issues. Regardless, it’s always best to consult your technician and be upfront about any metal that can’t be removed from your body.
With the right precautions, you can proceed with peace of mind and get clear, accurate scan results.
