Radiologists have warned that wearing magnetic eyelashes during MRI scans can be dangerous.
Magnetic eyelashes – one of the most sought after beauty trends – are attached with small magnets instead of glue.
Researchers have tested a few pairs of false eyelashes to discover that they have destroyed the images.
The magnetic force can also pull the eyelashes out of sight, which endangers the safety of the patient, tests suggest.
The team has called for the eyelashes add to list of prohibited items for the general procedure, in addition to jewelry and medical items.
MRI scans, used to detect various brain disorders, such as tumors, swelling or developmental problems, work by producing strong magnetic fields.

Scanners usually have a magnetic strength between 1.5 and 3 Tesla – the power of a fridge magnet is only 0.005 Tesla.
For this reason, patients are explicitly warned to remove all metal objects from their bodies, including watches, jewelry, piercings, dentures, and hearing aids.
If no precautions are taken, the scanner can pull objects there, warned the experts at Penn State Health Milton S. Hershey Medical Center.
This has resulted in people being pinched on the machine and even causing death in extremely rare freak accidents.
The radiologists, led by Dr. Einat Slonimsky and Dr. Alexander Mamourian said: & # 39; We strongly recommend placing a line over magnetic eyelashes in the MRI safety questionnaire and adding stops in the screening system to prevent anyone with these eyelashes, including personnel, from entering the MRI scanner room comes in. & # 39;
The lash sets work in two parts, with a false eyelash above it and the other under your natural lashes that click together.
Brands such as One Two Lash, founded by entrepreneur Katy Stoka from Miami, Lash FX and Ardell Lashes say that the customized eyelashes can be used over and over again.
We can wear eyelashes such as those sold by One Two Cosmetics multiple times. But researchers investigated a few pairs of counterfeits and discovered that they destroyed MRI images

Researchers from the radiology department at the center attached some magnetic eyelashes to a test device called a phantom.
The cylindrical object is designed to reflect how human tissue would react in imaging procedures.
They measured how the eyelashes handled compared to aneurysm clips, objects that were used to treat brain aneurysms but were not allowed in an MRI scan.
In comparison with the clips, the magnetic eyelashes damaged the image more, obscuring the entire phantom.
The eyelashes remained on the phantom during scanning. But when the phantom was removed from the scanner, a set of eyelashes loosened due to magnetic forces.

& # 39; Although our staff had little or no awareness of the existence of magnetic eyelashes, The Wall Street Journal reported that instruction about their use and application was the most popular beauty-related search on Google in 2018 & # 39 ;, wrote the authors .
In the American Journal of Roentgenology, they warned that radiologists should be aware of magnetic lashes to inform patients about the risks.
There is currently no evidence that someone has been seriously damaged by magnetic eyelashes during an MRI scan, the researchers said.
They added: & # 39; Although we have tested only one type of magnetic lashes, it is reasonable to assume that all such lashes will behave in this way, causing slightly less or somewhat more magnetic field distortion and that they are all are attracted by the static magnet. & # 39;
WHAT IS A MAGNETIC RESONANCE IMAGING (MRI) SCAN?
Magnetic resonance imaging (MRI) is a type of scan that uses strong magnetic fields and radio waves to produce detailed images of the inside of the body.
An MRI scanner is a large tube that contains powerful magnets. You lie in the tube during the scan.
An MRI scan can be used to examine almost every part of the body, including the brain and spinal cord, bones and joints, breasts, heart and blood vessels, and internal organs – such as the liver, uterus, or prostate gland.

The results of an MRI scan can be used to diagnose disorders, plan treatments and assess how effective previous treatments have been.
The largest part of the human body consists of water molecules, which consist of hydrogen and oxygen atoms. In the center of each hydrogen atom there is an even smaller particle, called a proton. Protons are like small magnets and are very sensitive to magnetic fields.
When you lie beneath the powerful scanner magnets, the protons in your body lie in the same direction, in the same way that a magnet can pull the needle of a compass.
Short bursts of radio waves are then sent to certain parts of the body, causing the protons to get out of line. When the radio waves are turned off, the protons are re-aligned. This transmits radio signals that are picked up by receivers.
These signals provide information about the exact location of the protons in the body. They also help to distinguish between different types of tissue in the body, because the protons in different types of tissue align at different speeds and produce different signals.
In the same way that millions of pixels on a computer screen can take complex photos, the signals from the millions of protons in the body are combined to create a detailed view of the inside of the body.
