It’s No Myth: MRIs Can Burn You If You Have Tattoos
Tattoos are no longer rare markings worn by veterans who visited far-off places. Today, both sexes sport decorative art and permanent makeup, which the Food and Drug Administration (FDA) classifies as tattoos.
Some think that the potential of receiving a burn from an MRI when you have a tattoo is a myth. The truth is that burns can happen. If you take precautions, however, they are very rare.
The inks in tattoos usually have some type of metallic base, whether it’s iron, titanium or copper.
While tattoos are generally safe, there have been instances in which patients undergoing MRI scans have developed burns in the area of their tattoo.
Alternately, patients with tattoos may not have a clear image in the area scanned if an iron oxide based ink covers it.
How It Happens
During an MRI, high-powered magnets create three-dimensional images of internal structures. Iron oxide, a ferromagnetic element, can cause disruptions within the magnetic field.
During the scan, the magnetic field can cause a reaction with the iron oxide in the ink causing an electric arc creating a stinging or burning sensation. In some individuals, a mild burn occurs with the affected area causing discomfort for less than 24 hours.
Tattoos at Risk
Iron oxide is most common in black and brown inks. Tattoos that have looping patterns, such as script letters or tails on animals are likely to interrupt the MRI field in some way.
Other tattoo patterns that can cause problems include those with large circular objects or multiple adjacent points.
If you have a tattoo that could cause trouble during an MRI, it doesn’t mean you should skip it.
Research studies on the adverse effects of an MRI on those with tattoos show the chances of running into trouble are slim. One study revealed that less than 2 percent of respondents reported any type of issue during their scan.
Preventive Measures
Nearly all MRI facilities use a screening form completed by patients before the scan. Be honest with your technician.
It’s their job to ensure your safety and relative comfort during the procedure. The technician will inform you of the associated risks and may offer you a cold towel to place over your tattoo to decrease any burning or stinging sensations.
Additionally, they may place a pressure bandage over your tattoo if it is located directly over the area they will scan. This prevents distortion to the image so the radiologist gets a clear picture of the internal structures.
As with all MRIs, the technician should remain in audio and visual contact with you at all times. Even if you can’t see them, they should be able to see you. If you feel any discomfort whatsoever, immediately let the technician know.
They will take the appropriate measures to ensure your comfort.
While the chances of actually getting a burn from an MRI is low, if you sport a tattoo you need to be aware of the possible risk.
Unless the tattoo continues to distort the images or causes a significant burn, you should be able to leave your MRI with great images, no burns and tattoos intact.
