Before employees and patients enter a magnetic resonance imaging (MRI) room, they are asked to remove all metallic objects from their person, however small.
The reason is in the name – MRI devices use exceptionally strong magnets that can turn all magnetic objects such as hairpins, jewelry and watches into dangerous rockets.
Strict precautions are therefore required to ensure the safety of all. However, as new products continue to hit the market, these boundaries are constantly shifting. Today there is a new cosmetic craze that could slip through the cracks.
A pair of radiologists now warns that magnetic eyelashes – where false eyelashes are attached to the eyelid with magnets instead of glue ̵
"We strongly recommend inserting a line of magnetic eyelashes into the MRI Safety Questionnaire and inserting stops into the screening system to prevent people with these eyelashes, including staff, from getting into the MRI scanner room." writes.
The recommendation is based on their new research that magnetic eyelashes, which were not removed before scanning, not only affect the resulting images, but may even endanger the patient.
Attaching two The researchers looked at how these products in an MRI environment compared to aneurysm clips, a kn, with magnetic eyelashes from the same manufacturer and a specially designed test device, a phantom, bypass its own medical device that can falsify the scans and for reasons of patient safety is not allowed in scanners.
Compared to the clips, magnetic eyelashes caused a much larger image distortion that obscured the entire phantom. And while all the eyelashes stayed on the device while scanning, one set of eyelashes actually broke away as the phantom was removed and moved toward the other.
Given how cheap and popular these new cosmetic products have become, the researchers warns that all radiologists should look for patients and employees with possibly false lashes of the magnetic type.
"Although our staff knew little to nothing about the existence of magnetic eyelashes, the Wall Street Journal reported that instructions for their use and application in 2018 were Google's most requested beauty search" the authors.
There is currently no evidence that someone has been damaged by magnetic eyelashes during an MRI scan. Nevertheless, the researchers point out that if these accidents do not happen, they are likely to be under-reported.
"Although we only tested one type of magnetic eyelashes, it is reasonable to assume that all of these eyelashes behave this way, and both cause less or a little more magnetic field distortion, and all of this is attracted to the static magnet," they conclude.
The article, which is currently available before printing, is published in American Journal of Roentgenology in November.
