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.

India’s RT-PCR testing system is capable of detecting the Bundibugyo strain of the Ebola virus, and the chances of missing a confirmed infection are very low when standardized protocols are followed, said health experts after the suspected Ebola case in Bengaluru involving a Ugandan woman tested negative.
The woman, who arrived in Bengaluru from Kampala, Uganda, on May 23, was suspected of Ebola infection after developing mild symptoms including body ache. She was shifted from a hotel to the state-run Epidemic Diseases Hospital on May 26, and her samples were sent to the National Institute of Virology (NIV), Pune. The tests today returned negative. India currently has no reported case of Ebola, the Health Ministry said.
Let’s take a look at how testing for Ebola takes place in India’s virology labs.
Speaking to HealthandMe, Dr. NK Ganguly, former Director General of ICMR, said that RT-PCR remains the confirmatory test for Ebola infection, while rapid diagnostic tests (RDTs) are mainly used for initial screening with limited sensitivity — of around 85-89 per cent.
According to him, the World Health Organization recommends that RT-PCR should only be carried out in specialized reference laboratories due to biosafety requirements. India currently has two designated Ebola reference laboratories — the National Institute of Virology (NIV), Pune, and the National Centre for Disease Control (NCDC).
"The Altona RT-PCR kit is the real star and is highly standardized. It rarely misses Ebola cases when proper protocols are followed,” Dr Ganguly said.
Bundibugyo is one of the strains of the Ebola virus currently linked to outbreaks in parts of Africa, including Uganda and the Democratic Republic of the Congo (DRC). The rare strain has caused over 900 cases and more than 200 deaths.
Dr. Ganguly said the incubation period for the Bundibugyo strain can range from six to seven days up to 15 days or even three weeks.
“If a person tests RT-PCR negative during this period, the chances of being infectious are lower. However, isolation is still necessary because there may be a short window period during which the infection may not be detected,” he said.
The expert added that travelers arriving from outbreak-hit countries should remain under quarantine even if their initial Ebola test is negative.
Dr. Ganguly explained that Ebola belongs to the filovirus family, which includes several strains such as Bundibugyo, Sudan, Taï Forest and Zaire viruses.
He noted that Ebola has a high fatality rate, with nearly 50 per cent of infected individuals dying from the disease. He added that the virus can spread through several body fluids including tears, saliva, milk and urine.
In the early stages, Ebola symptoms can resemble flu, malaria or other viral illnesses, including fever, cough, sore throat, headache, diarrhea, skin rashes and body ache, making early diagnosis difficult.
Dr. Ishwar Gilada, a Mumbai-based infectious disease expert, told HealthandMe that the Bengaluru patient’s symptoms were similar to common viral infections, which is why epidemiological history and travel exposure become critical in suspecting Ebola infection.
“The symptoms of Ebola can be a little confusing because they are just like any other flu,” Dr. Gilada said, adding that travelers arriving from Ebola-affected countries should remain under observation for up to 21 days.
Dr. Jatin Ahuja, Consultant, Infectious Diseases, Indraprastha Apollo Hospital, Delhi, told HealthandMe, there are no major loopholes in India’s Ebola PCR testing system, but there are certain limitations common to all diagnostic tests.
"One key limitation is the timing of testing. If RT-PCR is performed very early in the infection, there is a possibility of a false-negative result because the viral RNA levels may still be too low for detection," he said.
Dr. Ahuja also pointed out that test accuracy depends on whether the PCR targets are correctly aligned with the specific Ebola strain being tested. Improper alignment may reduce sensitivity.
He added that pre-analytical factors such as sample collection, storage, transport and RNA extraction also influence the final test outcome.
“Negative Ebola PCR substantially reduces concern, but interpretation always depends upon the clinical picture, travel history and exposure risk,” Dr. Ahuja said.

Hypertension is the “number one killer” in India, with nearly 1.6 million people dying from the condition every year, said Dr. Ambuj Roy, Professor of Cardiology at the All India Institute of Medical Sciences, New Delhi, today.
Speaking to media persons on hypertension, Dr. Roy said the deaths “linked to high blood pressure are five times higher than tuberculosis fatalities and exceed the combined toll of communicable diseases such as TB, malaria, dengue, and HIV”.
Calling hypertension a “silent but deadly disease,” he said most people remain unaware they have high blood pressure because symptoms are often absent.
“Ninety per cent of the time, hypertension does not cause symptoms. The only way to detect it is through regular screening,” he said.
Dr. Roy also cited the ICMR and NFHS-5 data showing that nearly 30 crore Indians are living with hypertension.
According to him, one in four adults in rural India and one in three adults in urban areas have the condition. However, “only one in three people know they are hypertensive, one in five receive treatment, and just one in twelve achieve proper blood pressure control below 140/90 mmHg”.
Dr Roy said lifestyle changes are driving the growing burden of hypertension in India. Poor diet, obesity, physical inactivity, air pollution, stress, and poor sleep habits are major contributors, particularly among younger people.
He highlighted excessive salt intake as a key concern. While the recommended salt intake is less than 5 grams per day, average consumption in India is around 12 grams daily. He also stressed the importance of potassium-rich foods such as fruits and vegetables, noting that most Indians fail to consume the recommended 400 grams of fruits and vegetables per day.
Further, the Cardiologist linked pollution exposure to rising hypertension rates. Referring to studies conducted by AIIMS in collaboration with IIT Delhi, Dr. Roy said areas exposed to crop burning showed a 15 per cent higher prevalence of hypertension.
Another study found that every 10 microgram increase in PM2.5 levels was associated with a 5 per cent higher risk of hypertension.
Dr. Roy said reducing blood pressure by just 10 mmHg can significantly lower the risk of
He also referred to the “TOPSPIN trial,” a large Indian hypertension study, which found that a single-pill combination therapy using two medicines reduced blood pressure by 30–40 mmHg and helped nearly 70 per cent of patients achieve blood pressure control.
The expert stated that around 70 per cent of patients may require long-term treatment or may need it lifelong. However, for nearly 30 per cent of people, hypertension can be reduced by stopping medication through:
Importantly, Dr Roy cautioned people against stopping blood pressure medicines abruptly once readings improve.
“Blood pressure is controlled because of the medicine. If you stop it suddenly, BP can rise sharply and may trigger a brain stroke or hemorrhage,” he said.
Dr. Roy also dismissed fears around side effects of antihypertensive medicines, calling them among the safest long-term drugs available. “The only side effect they have is benefits,” he remarked, adding that these medicines reduce the risk of heart attack, stroke, and kidney failure.
To reduce blood pressure naturally, the expert advised people to

The American Cancer Society (ACS) has updated its colorectal cancer testing guidelines, which bring new screening options for colorectal cancer. This will give the Americans two new options of stool-based tests and blood-based screening tests.
The ACS recommended colorectal cancer screening for citizens as the risk of the disease starts at the age of 45 and continues through age 75 for those with a life expectancy of 10 more years. Thus, to make colorectal cancer tests more accessible to the masses, the new guideline gives nod to blood-based screening tests and FDA-approved new stool sample kits.
Blood-based screening tests must be done in a doctor's office, while one can use stool sample kits for testing at home. Notably, colonoscopy is still the most accurate option for detecting colorectal cancer.
The new guidelines acknowledged the fact that people are likely to choose the most effective colorectal cancer screening test. But still about 20 million eligible Americans remained untested, according to the ACS.
ACS mentions that 1 in 5 colorectal cancer cases is seen in young adults; the new guidelines were a direct result of this huge problem. Though the one who will choose colonoscopy would only have to go through screening every 10 years, on the other hand, the gap between screenings will be every one, three, or five years, depending on the specific method of testing selected.
Some of the most commonly missed early signs include:
Ignoring such a red flag delays diagnosis and drastically reduces treatment success rates. A timely visit to a healthcare provider can change outcomes.
