Introduction
In the medical field, safety is paramount and wearing jewelry is considered a dangerous risk. For MRI technologists specifically, jewelry can potentially interfere with the images produced during scans. In addition, they can cause health hazards to both the patient and to MR technologists because of their strong magnetic fields.
For MRI scans it is essential that the scanner remains completely free of any metallic objects, including jewelry. Metallic objects like piercing jewelry, watches or belts will reduce the accuracy of an MRI scan due to interference in magnetic fields which alters images and shadows on the scans. This ultimately could lead to misdiagnosis due to artifacts or inaccuracies in imaging results. Not only this, but MRI pulses also create electrical currents that can cause serious injuries when coming into contact with a metallic object and thus must be removed before scanning a patient.
It is important for MRI technologists to be aware of these potential risks when donning jewelry for an exam; embarrassment or discomfort should never take precedent over patient safety and quality imaging results. To ensure compliance during exams, many hospitals have implemented strict procedures whereby all metallic objects must be removed prior to entering an MRI suite—this includes not only recognizable items such as watches or rings but even less visible items such as pierced earrings or body piercings located near sensitive areas where exposure restricts testing accuracy.
It is vitally important that radiographers pay full attention to these regulations so that imaging processes remain safe, secure and consistently reliable for both medical staff and patients alike.
Safety Regulations
Magnetic Resonance Imaging (MRI) technologists must follow safety regulations set by the American College of Radiology and other organizations when working with MRI equipment. These regulations provide guidance on the use of jewelry and any accessories worn in the MR environment.
Examples of prohibited items include necklaces, rings, body piercings, watches, electronics, keys and wallets. The only acceptable jewelry and accessories worn by MRI Technologists are wedding bands, medical alert tags and pins that can be secured so they do not hang or move freely. Any hair accessories have to be either plastic or covered with fabric to prevent interference with the imaging system. Earrings are not allowed unless they are tendonitis clips that fit over an earbud and must also be covered with fabric. Watches should never be worn while in the MRI room.
Benefits and Limitations of Jewelry
Advantages: Wearing jewelry during MRI scans can help set the patient at ease since it reminds them of home and creates a sense of familiarity. Jewelry can also be used to remind the patient that they are in a safe place because MRI technicians typically wear watches or other pieces of comfortable, everyday jewelry such as wedding rings, necklaces, and bracelets.
Disadvantages: Unfortunately, some jewelry can interfere with imaging during an MRI scan when certain metals become magnetized—causing artifacts on the scan or making it difficult for the radiologist to make an accurate diagnosis. Examples of sensitive jewelry that could affect an MRI scan include hearing aids, pacemakers and other implanted medical devices embedded with metal, large earrings made from metals such as nickel, some watches, steel toe boots and shoes, and copper/brass buttons.
Requirements by Location and Imaging Equipment
The regulations for MRI techs wearing jewelry can vary depending on what type of imaging equipment is being used and which location the tech is working in. For example, at many hospitals, the rules prohibit all staff from wearing any kind of jewelry that could be attracted to the magnetic field produced by the MRI machine, such as a stainless steel watch or bangle. This also prohibits any electronic devices from being worn on-site, such as cell phones and other technical gadgets.
In some locations, such as diagnostic centers that use open MRI machines, it may be permissible to wear lightweight jewelry made out of non-magnetic metals, such as bronze or gold. However, even these items must be inspected before entry into the MRI room in order to confirm they are safe and suitable for use in that environment.
Additionally, speaking generally across most facilities located anywhere in the world, tattoos with metallic ink are not allowed inside MRI rooms since they can also cause artifacts in the imaging data due to their conductivity when introduced to a magnetic field. Finally, if techs wear piercings containing stainless steel, titanium or another metal likely to be attracted to a magnet, they should remove these items prior to entering an MRI room–just like any other piece of jewelry.
Guidelines for Technologists
When it comes to wearing jewelry during Magnetic Resonance Imaging (MRI) scans, safety should be of utmost concern for MRI technologists. Since anything that is not made of MRI safe materials can potentially interfere with the imaging process, it is important to abide by the guidelines set in place by the hospital or facility in which an MRI technician works.
One general guideline is to choose jewelry pieces which are small so they don’t pose a greater risk of interfering with the imaging. Jewelry made up of plastic or cloth—which contain no potential metallic components—is considered safe and can often pass through an MRI scanner without issue. Additionally, necklaces should be taken off before scanning, as they can pose a choking hazard while in the scanner if they get entangled with any body parts.
Rings and earrings made from non-metallic materials are also accepted as long as there are no loops found in them . Any kind of metal found on clothing or jewelry must be avoided completely as it can cause significant distortion artifacts that will disrupt the scan process and make images unrecognizable due to severe signal loss. Finally, all jewelry pieces should be carefully secured prior to scans, so as not to risk potential secondary magnetic fields or hot spots that may interrupt normal imaging processes.
Wrap Up
When working with MRI technology, it is important to follow MR safety regulations. Wearing jewelry while working in an MRI environment can be dangerous and should be avoided. Also, any metal objects, such as keys and cell phones, must be kept away from the patient and MRI equipment. This is to ensure that patient safety, imaging quality, and accuracy are not compromised. It is essential for MRI technicians to adhere to these strict regulations in order to keep patients safe and to ensure that their images are of the highest quality.
