Will an MRI rip out piercings?

While dermal piercings are believed to be too small to present a risk as a result of heating during MR scanning, patients will be warned about heating as a precaution. When patients attend for MRI, they must be asked if any of their dermal piercings are magnetic. Any magnetic components must then be removed.

Considerations for 1.5T and 3T MRI of patients with dermal piercings

Must read: What this policy does not cover / notable exceptions

This policy does not cover patients with body art, tattoos or cosmetic beauty products.

Must read: What the policy covers

This policy considers 1.5T and 3T MRI scanning of patients with dermal piercings.

Must read: The MR safety policy

MRI scanning of a patient with dermal piercings is not ideal as some dermal piercings can have magnetic components and so may feel a significant pull on the skin if allowed to enter the MR Environment. Dermal piercings may also cause distortions within the imaging field of view. While dermal piercings are believed to be too small to present a risk as a result of heating during MR scanning, patients will be warned about heating as a precaution.

Screening to identify ferrous or magnetic dermal piercings

When patients attend for MRI, they must be asked if any of their dermal piercings are magnetic. Any magnetic components must then be removed. Following this, a final check with the handheld magnet should be done to confirm all ferrous or magnetic components have indeed been removed. If further components are identified by the handheld magnet as being either ferrous or magnetic then these must be removed prior to entering the MR Environment.

Screening for non-ferrous and non-magnetic dermal piercings

Following the screening process above for ferrous or magnetic dermal piercings, once these implants have been ruled out or removed, proceed as follows with non-ferrous / non-magnetic dermal piercings. If the patient is unable or unwilling to remove their non-ferrous/non-magnetic dermal piercings prior to scanning then scanning may proceed provided patients are advised to report any unusual sensations or heating in the implant area that occur during MR scanning. They should do this by pressing the staff call button.

What are the disadvantages of diapers?

Disposable diapers cause waste, since they aren't recyclable. However, some diapers are compostable, meaning they break down over time. These diapers take more work and cost more, but they're still technically disposable and mean parents avoid plastic waste. Potentially more irritation.

Cost. The cost of disposable diapers causes many new parents to complain. The average baby can use as many as 2,700 diapers per year! That adds up fast, especially if you use brand-name diapers. On the other hand, you only need to buy reusable diapers once, so they quickly pay for themselves. Waste. Many parents today realize their impact on the environment and try to minimize it. Disposable diapers cause waste, since they aren't recyclable. However, some diapers are compostable, meaning they break down over time. These diapers take more work and cost more, but they're still technically disposable and mean parents avoid plastic waste. Potentially more irritation. The plastics and dyes in disposable diapers may sometimes give your baby a rash, especially if they have sensitive skin. Not every disposable diaper will do this, but “hypoallergenic” diapers that are less likely to bother your baby are also more expensive in most cases. Reusable diapers, on the other hand, are less likely to contain these allergy-causing dyes. Fragile. You should only use disposable diapers for a few hours. This means that they're not always sturdy. It’s easy to accidentally break the tabs that hold the diaper together or for your baby to loosen the diaper while crawling. Fragile diapers mean more leaks or more risk of falling off and causing a mess.
