MRI scans are strong diagnostics with high-definition images of what lies inside a body. Strong magnetic fields require precaution, as brought out by an instance where a young woman suffered very serious injuries due to an oversight in a metallic core within a silicone sex toy that she happened to have before the MRI scan. This makes a stark reminder about the potentially deadly consequences of missing metal objects when such procedures are being performed. In April 2023, a 23-year-old woman went into an MRI with a silicone plug containing a metal core that was not known.
She thought that the item is made entirely out of silicone according to the advertising. However, the strong magnetic field of the MRI machine interacted with the hidden metal, dragging the object through her body and causing excruciating pain. According to reports from the U.S. Food and Drug Administration (FDA), the scene was harrowing, with the woman screaming in agony and requiring immediate hospitalization. Despite pre-scan screenings, which are routine prior to a scan, the patient did not inform the facility that the object existed because he presumed it was purely non-metallic. This caused serious injuries that led to the patient's law suit against the manufacturer for deceitful misrepresentations of material content.
MRI machines employ magnets between 0.5 to 3 Tesla (T). This is thousands of times stronger than the Earth's magnetic field. The tremendous force causes ferromagnetic materials, like iron and nickel, to be magnetized quickly and become strongly attracted toward the magnet. Objects as small as hairpins or paper clips will accelerate at 40 miles per hour inside the magnetic field.
The force can lead to catastrophic injuries in items lodged within the body, such as metallic implants or foreign objects. Metallic cores within devices, like pacemakers or intrauterine devices, must be disclosed to radiologists to prevent such complications.
On these claims, Dr. Adam Taylor, a specialist in human anatomy, weighed his words in a international health website and added that the distance away and mass of this object would increase its velocity towards that of sound, "The acceleration would be phenomenal, but with a metallic core, it can't go anywhere near supersonic speeds. As for the size, the magnetic acceleration to the internal soft tissues would ensure that there could be severe intracranial trauma."
The injuries inflicted in this case likely involved damage to major blood vessels, nerves, or organs, highlighting the devastating impact of even minor oversight during an MRI scan.
This is not an isolated case. There are documented cases of metallic objects causing serious damage during MRI scans with a 65-year-old man with schizophrenia swallowed metal objects, including sockets and a hinge pin. The powerful magnetic field during an MRI scan caused the objects to rupture his stomach, resulting in serious injuries.
A toddler who ingested 11 small magnets perforated his bowel while undergoing a scan, making his case unique. In another deadly but extremely rare incident, there have been people who hide a firearm on themselves during MRI procedures. Magnetic attraction can trigger a discharge in a weapon and has led to some fatal injuries.
These cases emphasize the very strong need for adequate screening and patient education prior to an MRI.
Medical professionals have been trained to avoid risks. This is by properly screening a patient for metallic objects. In general, most pre-scan protocols include:
The case emphasizes the importance of product labeling by manufacturers, especially those products that are likely to unintentionally cause harm to health. The patient's assumption that her device was 100% silicone points to a larger problem in consumer markets with misinformation.
It also reminds the patients to report any possible dangers to the medical professionals, no matter how the objects look non-metallic. In sensitive cases, patients can request private discussions with healthcare providers to ensure safety without discomfort.
In the end, it is a joint effort from manufacturers, healthcare professionals, and patients that can prevent such tragedies. Manufacturers must ensure truthful marketing, while healthcare providers should educate patients about the dangers of metal objects in MRI settings. For patients, understanding the risks and actively participating in pre-scan disclosures can be lifesaving.
This young woman's experience is a sobering example of the unforeseen dangers posed by MRI machines when precautions are overlooked. It serves as a wake-up call to address gaps in patient awareness, medical protocols, and product transparency. By learning from this incident, the medical community and the public can work together to ensure MRI scans remain a safe and effective diagnostic tool.
Low resting heart rate is a common occurrence in physically fit people. (Photo credit: AI generated)
Stroke is a medical emergency that can lead to long-term disabilities if not diagnosed in time. Yet, many do not realise that a high resting heart rate could be linked to a higher risk of stroke. Once a concern for the elderly, stroke can now occur in young people as well, and doctors say that this is a worrying trend. Now, findings from a large study indicate that a low resting heart rate could be just as bad when it comes to stroke risk, challenging the common perception that fewer heartbeats per minute guarantee good heart health. But how can you be certain of your heart rate?
The common idea, according to doctors, is that a higher heart rate is linked to a higher stroke risk. However, the relationship is not linear. Researchers presented the results at the European Stroke Organisation Conference. They stated that they had identified that people who were at a relatively lower risk of stroke had a heart rate between 60 and 70 beats per minute. Resting heart rate refers to the number of times the heart beats in a minute when the body is at rest, such as when sitting or lying down. The normal heart rate for adults is 60 to 100 beats per minute.
For this, researchers analysed 460,000 people in the UK Biobank, aged 40 to 69 years. Experts monitored participants for an average of 14 years and, during that time, recorded over 12,000 stroke cases. When compared with people whose heart rate was in the middle range, researchers noted that people with a heart rate of 90 had a 45 per cent higher risk of stroke. Surprisingly, people with a heart rate of less than 50 had a 25 per cent higher risk of stroke. This was even after scientists adjusted for other stroke risk factors, such as blood pressure, age, and atrial fibrillation.
When the data was broken down by stroke type, a low heart rate was linked to ischaemic stroke risk, a condition caused by blocked blood circulation to the brain. It is the most common type of stroke. A higher heart rate, on the other hand, was linked to both ischaemic and haemorrhagic strokes, the latter characterised by bleeding in the brain. A low heart rate can lengthen pauses between heartbeats, reducing steady blood flow to relatively smaller brain vessels and making blockages more likely. The symptoms are:
A higher heart rate can also increase stress on blood vessel walls, making them more prone to bleeding. However, researchers say that most of this is still hypothetical — a low heart rate could still be indicative of fitness in people who work out regularly. Doctors say that a low heart rate is a good way to measure heart disease risk. While the findings are observational, it cannot be conclusively said that a high or low heart rate can directly lead to a stroke. More research is required in this area before a conclusion can be reached.

Countries across Europe, Africa, and South America are tracing contacts of passengers linked to the MV Hondius cruise ship hantavirus outbreak after multiple deaths and suspected human-to-human infections raised global concern. However, the World Health Organization (WHO) says the risk of a Covid-like global spread remains low.
The latest hantavirus outbreak has so far infected eight people, including three deaths, among the 150 people aboard the MV Hondius cruise ship.
The Andes strain of hantavirus, which can spread from person to person, has been identified in two people who disembarked from the cruise ship.
While hantavirus carries a mortality rate of up to 40 percent, the WHO stated that the overall global risk remains low.
More than two dozen passengers left the ship before learning they may have been exposed to the virus. Countries are now tracing them to prevent potential spread to the general public. The virus can spread through close contact, as seen in the MV Hondius cases.
According to WHO official Shenaaz El-Halabi, authorities are tracing passengers linked to an international flight and the cruise ship, involving 16 countries and dozens of contacts.
More than 60 percent of identified contacts have already been followed up on, while investigations continue using epidemiological and laboratory data.
US
At least 23 passengers from the hantavirus-affected MV Hondius cruise ship returned home, including several to the United States — and one of them has already fallen ill.
The travelers reportedly did not know they had been exposed to the deadly virus when they disembarked during the ship’s stop at Saint Helena, a remote island in the South Atlantic, on April 23.
“There are 23 people wandering around there, and until three days ago, no one had contacted them,” a passenger still aboard the ship told the Spanish newspaper, El País.
“The Australian went back to Australia, the one from Taiwan to Taiwan, the Americans to all corners of North America. The Englishman to England, the Dutch to their homes… I don’t remember the rest,” the passenger added.
People in at least three US states — Georgia, Arizona, and California — are being monitored for possible hantavirus exposure after the outbreak aboard the MV Hondius, though none have shown symptoms, according to the New York Times.
The Georgia Department of Public Health said it is monitoring two residents who “are currently in good health and show no signs of infection.”
The Arizona Department of Health Services confirmed that one resident who traveled on the ship is being monitored and is not symptomatic.
“There is no information that California residents are ill or infected. At this time, the risk to public health in California is low,” Robert Barsanti, a spokesman for the California Department of Public Health, said.
According to Dr. Jay Bhattacharya, Director of the US National Institutes of Health (NIH), “Hantavirus is not spread by people without symptoms, transmission requires close contact, and the risk to the American public is very low.”
UK
According to Oceanwide Expeditions, the operator of MV Hondius, 19 passengers and four crew members aboard the ship were British nationals.
One of them, a 56-year-old British man, was among the three passengers evacuated from the ship on Wednesday and is reported to be in stable condition.
The UK Health Security Agency (UKHSA) said two British nationals are self-isolating at home after potential exposure to hantavirus on the cruise ship. The pair had disembarked earlier in the voyage and currently shows no symptoms.
UKHSA said contacts linked to their return journey, including passengers on a flight from Johannesburg, are being traced. The agency added that the risk to the general public remains very low.
Switzerland
Swiss officials are tracing the contacts of a man hospitalized in Zurich with the Andes strain of hantavirus, according to reports.
The patient became ill after returning from a three-week April cruise that traveled from the southern tip of South America to the South Atlantic island of St. Helena.
The authorities said the patient’s wife has not shown symptoms but is self-isolating as a precaution.
Argentina
Health investigators in Argentina believe a Dutch couple may have brought the virus aboard after possibly contracting it through rodent exposure during a bird-watching tour near a landfill in Ushuaia days before the ship departed from Argentina on March 20. Both the husband and wife later died.
Argentina has one of the highest reported incidences of hantavirus in Latin America, according to the WHO. Authorities there are continuing efforts to trace the source of the outbreak.
The Argentine Health Ministry reported 101 hantavirus infections since June 2025 — roughly double the number reported during the previous year, according to The Guardian.
A case of testicular implant may change the way infertility is managed. (Photo credit: AI generated)
Radiation and chemotherapy might be lifesaving for millions of children globally, but the cost of these intense therapies is much greater. Therapies like these spike the risk of infertility in adulthood — one third of men on these treatments are considered 'azoospermic' after pube—onehis means that when they ejaculate, it lacks any viable sperm. But on the bright side, a medical team at the University Hospital Brussels and the Free University of Brussels (VUB) found that they successfully restored sperm production in one such patient.
In a new case study, which is now in peer review, researchers explained how they treated a male patient with no viable sperm by retransplanting his own childhood testicular tissue into his adult testicle. The anonymous patient was born with sickle cell anaemia, an inherited disease that can be managed with small chemotherapy doses or through a donated bone marrow transplant. In 2008, before the treatment, the patient's family consented to the removal of one of his testicles and had it frozen for future use. The patient was 10 years old at the time.
Later, in 2022, the patient returned to Brussels IVF at VUB hoping to become a father. However, it was found that there was no viable sperm in his testicle. He requested a transplantation of the frozen tissue. In 2025, during the trial, he underwent surgery to receive four tissue grafts within his testicle and four in his scrotum. A year later, some of these produced motile, mature sperm. However, only the parts of the testicle with the transplants held viable sperm — and these were not connected to the patient's sperm duct. The sperm, therefore, was not likely to reach his semen. Consequently, IVF was the only option for the patient to have a baby — but the silver lining was that, if he wanted a baby, it was possible.
According to doctors, adults who undergo radiation and chemotherapy must undergo sperm banking in the conventional way. However, before puberty, patients are not fit for freezing sperm, as the body is not producing mature sperm yet. In childhood, the testicles contain spermatogonial stem cells (SSCs) — these have the potential to become sperm later. Freezing this tissue could be a way to preserve fertility in younger patients who are prone to infertility.
The University Hospital Brussels became the first-ever hospital to introduce this practice in 2022. Years later, other hospitals followed suit and offered cryopreservation for over 3,000 boys globally. The samples collected were banked for future studies and research to determine whether the approach is, in fact, viable or not. For many patients, it is the only way to restore existing fertility. Although a single patient is not enough to prove that the procedure works, the Brussels story offers hope for men dealing with infertility.
Animal studies have found that the grafts have a shorter lifespan. However, how long they can last in humans is still unknown; furthermore, researchers are yet to ascertain whether these sperm can lead to healthy babies. This step is important for further research on preserving fertility.
