What Is an MRI Safety Accident?

An MRI safety accident refers to any unintended event or mishap that occurs during an MRI scan procedure, leading to injury, harm, or potential complications for the patient or staff. While MRI scans are generally safe, several risks and potential issues can arise, which can result in accidents.

Continue reading to learn more or jump straight to one of the most recent case studies below for more information.

How do MRI accidents occur?

MRI accidents occur when there is a violation of one or more MRI safety guidelines, which are designed to mitigate the inherent risks associated with the MRI environment. Understanding these risks and how accidents can occur involves recognizing the main hazards of the MRI system. The most significant risks associated with MRI include the powerful magnetic field, induced currents caused by rapidly changing secondary magnetic fields, RF energy, and loud MRI sounds (up to 120 dB).

What can go wrong during an MRI?

An MRI scan is generally safe, but there are various risks and potential complications that can arise during the procedure. Here is an extensive list of what can go wrong during an MRI:

• MRI burns
• Heating of implants
• Projectile events
• Dislodged implants
• Induced electrical currents
• Incorrect patient positioning
• Adverse reactions to contrast agents
• Nephrogenic Systemic Fibrosis (NSF)
• Hearing damage
• Pinched or crushed fingers
• Image artifacts
• Patient falls
• Image quality issues
• Scanner malfunctions
• Complications from sedation

These potential risks highlight the importance of thorough patient screening, adhering to all MRI safety guidelines, and ensuring the MRI facility is equipped to handle emergencies.

1. Neuromodulation IPG Stuck In MRI Mode (June 2024 Texas, USA)

A neuromodulation implantable pulse generator (IPG) was placed in MRI mode using patient’s personal phone. The mobile app used to connect to the IPG was downloaded by another device in the proximity and attempted to connect to the IPG resulting in a loss of Bluetooth connection between the patient’s phone and the medical implant. As a result, the IPG was unable to exit MRI mode and the following messages displayed: “no generator found” and “no generators have been added.”

Lessons Learned

The recent adverse incident report underscores the challenges medical device manufacturers face when designing products that balance ease of use with robust security features to prevent unauthorized access. When these difficulties are compounded by the dynamic nature of real-world applications and user inputs, the hurdles for both manufacturers and regulators can seem insurmountable. However, the FDA has demonstrated impressive results by collaborating with medical device manufacturers to address reported issues promptly and to develop safer products. This case exemplifies the complex task of anticipating compatibility issues with emerging technologies in our rapidly evolving environment.

2. Infant Suffers 2nd Degree Burns During MRI (Jan 2024 Sydney, Australia)

A young girl sustained a second-degree burn on her leg, which was revealed when she awoke from sedation and began crying uncontrollably. The concerned parents, frustrated by the initial treatment, sought a second opinion at a different hospital. Shortly after, the child was diagnosed with a second-degree contact burn in the form of two black dots and secondary burns just inches away. The latest update reports no known cause for the MRI burns.

Lessons Learned

After examining the pictures of the alleged incident, it seems evident the young patient suffered contact burns. It’s important to examine the procedures used for pediatric MRI patients, specifically the types of coils employed (such as when head coils, or small flex coils, are used for babies), as well as padding techniques and patient positioning. Thermal incidents account for over 60% of all MRI accident reports, so such cases are unfortunately not uncommon. The two burn marks observed can result from patient contact with the MRI coil, the introduction of foreign metals into the MRI environment, or creating loops with the body or objects, which can cause local heating and lead to serious burns. MRI technicians are trained in proper patient positioning and padding to minimize the risk of contact burns. For further information, refer to the MRI safety statistics section below.

3. Woman Shot With Own Gun During MRI (December 2023 Wisconsin, USA)

A 57-year-old woman suffered a minor injury when a loaded gun she brought to an MRI appointment accidentally discharged, shooting her in the buttocks. According to a report filed with the U.S. Food and Drug Administration, the woman had been asked if she had any metal objects before the scan and had answered no. The gun went off during the MRI, causing a superficial wound as the bullet passed through the fleshy part of one buttock. The incident, which occurred in June, was recently reported to the FDA in December 2023. The patient is reportedly healing well from the injury.

Lessons Learned

The patient in this case was lucky to have only suffered minor injuries from what could have been a disastrous event. As you will see in the case studies below, patients that accidentally bring guns into MRI scan rooms can be struck and killed when guns are sucked into the powerful magnet.

Why are guns so dangerous around MRI scanners?

The most significant risk arises from metal components in a gun being drawn into the powerful MRI magnet. This hazard is further complicated by the gun’s tendency to align with the longitudinal axis of the magnetic field, either pointing away from the magnet, where the patient lies, or facing towards the rear of the magnet. This alignment increases the risk of injury if the gun were to accidentally discharge. In reported incidents, the magnetic field has caused safety mechanisms to disengage, leading to accidental discharges when guns are pulled into the MRI magnet, although many incidents have not resulted in discharge. Currently, there are no reliable statistics comparing incidents where the gun discharges versus those where it does not. We will update this section as data becomes available. For now, consider all firearms in or near an MRI scan room as potential hazards with the risk of accidental discharge.

4. Inmate, Guard Stuck To MRI Machine (October 2023 Arizona, USA)

Arizona inmate (patient) suffered significant injuries when metal shackles were not removed before her MRI scan, causing her to become painfully stuck to the machine. A prison guard who tried to assist also became trapped when he entered the MRI scan room. The patient required emergency treatment for her injuries, including a deep cut and bruises. The imaging center where the incident occurred is exempt from state health department regulation due to a “physician-owned” claim, however further investigations into the matter are underway. Arizona health officials are re-evaluating this exemption and will require privately-owned imaging centers to obtain proper licenses and adhere to safety regulations.

Lessons Learned

To provide full context, I have personal experience working with the MRI system and site in question. Over my 15 years in installing and servicing MRI systems, I visited this specific site multiple times between 2014 and 2019 to perform various maintenance tasks. I can confirm that the organization is dedicated to delivering top-tier medical imaging technology and is a leading imaging center in the Phoenix, AZ area. They are committed to hiring skilled imaging professionals and maintaining stringent patient safety and screening procedures. Throughout my career in biomedical imaging repair, I have not encountered any safety issues at this facility, or any other imaging facility owned by this. During inspections, I rarely found foreign metal objects in or around the MRI magnet, highlighting their strong adherence to patient screening standards.

However, this case underscores the critical importance of MRI safety training for all individuals entering the MRI Zone 3 environment, not just the MRI technologists. While metal detectors can identify potential hazards, strict adherence to safety signage prohibiting all metal items is essential to prevent serious or potentially fatal accidents.

Additionally, this incident highlights the need for improved MRI accident reporting standards and regulatory oversight in medical imaging. While Arizona is currently in the spotlight, the issues of inadequate oversight and optional MRI accident reporting affect facilities across the US and Canada. Presently, the FDA only requires reporting of MRI accidents that result in serious injury or death. However, the FDA is actively working to enhance medical device safety, and improved incident reporting is a crucial part of this effort.

5. Sex Toy Injures Patient During MRI Scan (July 2023)

The U.S. Food and Drug Administration received a report of an MRI accident involving a silicone and metal sex toy. The incident occurred when a patient, who had been screened for metal but did not disclose the presence of a “butt plug,” experienced severe discomfort during the MRI. According to the report, the patient began screaming as the MRI technologist was removing the table, complaining of nausea, pain, and feeling faint. The report did not specify the patient’s injuries, but it noted that an ambulance was called, and the patient was taken to a nearby hospital. The FDA report on this adverse event is available for review.

Lessons Learned

This incident gained widespread attention on social media, quickly going viral across various platforms. It underscores the critical importance of never bringing untested products into the MRI scan room, even if they appear to be free of metal. Additionally, it highlights issues related to copyright law concerning patient images, as well as the professional and ethical standards breached when medical staff share patient images on social media. The viral post has since been removed from Tik Tok.

6. Man Killed With Own Gun During MRI (February 2023 Sao Paulo, Brazil)

A lawyer in Brazil was tragically killed when a concealed handgun he was carrying discharged during an MRI scan, shooting him in the abdomen. Despite being asked multiple times, both verbally and in writing, to remove all metal objects before entering the MRI room with his mother, the 40-year-old man retained the weapon. The gun went off when the MRI machine was activated, resulting in fatal injuries. The imaging facility emphasized that all standard accident prevention protocols were followed. The man, who was licensed and registered to carry the gun, was taken to São Luiz Morumbi Hospital but succumbed to his injuries after three weeks. It remains unclear whether this incident was due to a disregard for warnings or simple forgetfulness. However, it highlights the need for collaboration between patients and imaging professionals to ensure a safe MRI environment.

Lessons Learned

In simple terms, no firearm should EVER be brought into an MRI scan room. This includes polymer handguns. Contrary to the misconception that polymer guns are made entirely of plastic, they still contain ferrous metals in parts like the barrel, firing pin, frame, and ammunition. When these firearms are brought near an MRI magnet, they can be forcefully pulled into the machine, potentially causing severe injury or death. Additionally, the magnetic field can align the gun with the MRI’s main axis, meaning the gun could end up pointing directly at the patient, and possibly firing, as it is drawn into the magnet.

7. Nurse Crushed by Gurney During MRI (February 2023 California, USA)

According to a Cal/OSHA investigation, a nurse was pinned between the bed and an MRI machine, resulting in severe crushing injuries. The nurse suffered a deep laceration that required surgery to remove two embedded screws. The patient who fell from the bed during the incident was unharmed.

Investigation records indicated that some employees had not received required safety training and that the facility failed to test the door alarm annually as recommended. The Department of Public Health’s investigation criticized the facility for a “culture of unsafe practices” due to numerous safety failures. Sources have claimed that this was not the only incident at the Redwood City hospital.

Although the CDPH began an investigation, it was referred to the U.S. Centers for Medicare and Medicaid Services (CMS). Cal/OSHA also reviewed the case, but the CDPH admitted that no state-level administrative actions were taken against the facility.

Lessons Learned

This recent event garnered significant attention from news sources and underscores the challenges encountered in a dynamic clinical setting. While investigations are ongoing, the incident highlights the critical need for thorough training of all staff who may interact with the MRI environment. Proper labeling of MRI-safe or MRI-compatible components is essential to prevent confusion and enhance safety in such situations.

8. Certain Masks Can Cause Serious MRI Burns (July 2022 Study)

A study conducted by scientists at Cardiff University in July 2022 revealed that certain types of face masks are unsafe for use in and around MRI machines. The researchers tested eight different commercially available filtering facepiece (FFP3) respirators and found that five of them contained magnetic components deemed ‘MRI unsafe.’ Many of these masks feature metal nose strips or clips for shaping, metal staples for securing elastic straps, or antimicrobial coatings containing metals like silver or copper. These metal components can interact with the powerful magnets in MRI machines, potentially causing issues such as displacement of the mask, flying metal parts, or even serious burns to the patient.

9. 60 Year Old Man Killed by Oxygen Cylinder During MRI (October 2021, South Korea)

In October 2021, a tragic MRI accident occurred at a South Korean hospital, resulting in the death of a 60-year-old man. According to KBS News, an oxygen cylinder that had been brought into the MRI suite on a pallet with the patient was inadvertently moved during the scan. The cylinder, which weighed over 60 kgs, was drawn into the MRI machine and struck the patient in the head, causing fatal injuries. The incident may have been exacerbated by a malfunctioning inbuilt oxygen supply system, necessitating the use of the external cylinder. Additionally, there were no CCTV cameras in the MRI room to provide further insights into the accident.

10. Nurse, Guard, Vest, Handcuffs, and Baton Stuck To MRI (October 2019 Luleå, Sweden)

In October 2019, a tragic incident occurred at Sunderby Hospital in Luleå, Sweden, involving a mobile MRI unit. According to Dr. Hans Ringertz, PhD, professor emeritus at the Karolinska Institute, a nurse became trapped in the MRI gantry when a weighted vest, containing metal weights, was accidentally pulled into the machine. The nurse’s head was caught outside the scanner while the vest strap became wrapped around his neck, leading to unconsciousness.

The situation was initially detected when the nurse’s screams and a hand inside the scanner alerted a patient, who then attempted to assist. Despite the patient’s efforts and the intervention of a security officer, the nurse remained stuck. The guard eventually used a knife to cut the strap and free the nurse. In the process, some of the guard’s equipment was also sucked into the MRI machine, further complicating the issue.

A police report finalized on February 24 indicates that nickel-plated steel handcuffs and a baton were pulled into the scanner during the rescue attempt. There were media claims of a handgun being drawn into the scanner, but forensic information does not show any evidence to support this claim. The hospital reports that the weighted vest, worn by the nurse, was inadvertently brought into the MRI unit by the patient, who had mistakenly believed it was safe. The vest, which contained 13 ferrous metal weights, was ultimately responsible for the nurse being pulled into the scanner.

11. Metal Hamper Strikes Patient’s Face During MRI (June 16, 2019 Massachusetts, USA)

On June 16, 2019, an MRI patient at Lowell General Hospital Saints Campus in Lowell, Massachusetts, suffered a facial fracture after a metal hamper was accidentally introduced into the MRI room. According to reports, an MRI technologist mistakenly brought the wrong linen hamper into the scanning area. The metal hamper was drawn toward the MRI’s powerful magnet and struck the patient in the face, resulting in a fractured facial bone.

12. Handgun in MRI Injures Patient (June 2018, New York, USA)

In May 2018, a man in Long Island, New York, sustained leg injuries when a handgun he was carrying accidentally discharged in an MRI scanning room. The patient visited a open MRI for a scan. Despite being asked to remove any metal objects multiple times before the procedure, the patient’s .38-caliber handgun fired while it was in his pocket, due to the strong magnetic field of the MRI machine. The patient had a valid gun license, however, they were arrested shortly after by police and charged with reckless endangerment.

13. Man Dies After Being Crushed By Oxygen Cylinder In MRI (January 2018, Mumbai City, India)

In January 2018, a 32-year-old Indian man tragically died after being sucked into an MRI machine while carrying an oxygen cylinder at BYL Nair Hospital in Mumbai. The Bombay High Court ordered the Brihanmumbai Municipal Corporation (BMC) to pay Rs 10 lakh in interim compensation to the patients family. According to Mumbai police, a doctor and a junior staff member have been arrested under Section 304 of the Indian Penal Code for causing death due to negligence. Preliminary reports indicated that the patient’s death was caused by inhaling liquid oxygen that leaked from the cylinder.

14. Veteran Injured By Gun In MRI (December 2015 Indiana, USA)

In December 2015, a veteran was injured at the Richard L. Roudebush Veterans Affairs Medical Center in Indianapolis when a handgun he brought into the hospital accidentally discharged in his pocket while he was in a procedure room, possibly inside an MRI suite. According to the report, the wound was not life-threatening.

15. 13 Year Old Boy Loses Thumb In Routine MRI (August 2015 Amiens, France)

In August 2015, a 13-year-old boy lost his thumb due to a serious error at CHU Hospital in Amiens, France. During a routine MRI scan, a monitoring device was mistakenly left attached to the young patient’s thumb, causing severe burns that went “through to the bone.” The boy, who was under anesthesia during the MRI procedure, did not realize the severity of the injury until he began screaming in pain. According to his mother, the medical staff failed to inform her about the accident, leaving the patient to endure several hours of intense pain in the emergency room. As a result, the patient ultimately lost his thumb.

16. Two Hospital Workers Trapped in MRI for Four Hours (December 2014 Mumbai, India)

In 2014, two hospital workers were pinned for four hours between a powerful MRI machine and a metal oxygen tank at Tata Memorial Hospital in New Delhi, India. The 4-foot oxygen tank was pulled across the room by the MRI’s magnetic field, leaving a porter and technician seriously injured. The incident occurred while a patient was being wheeled in for a routine scan. According to reports, the porter was asked to retrieve an oxygen mask but mistakenly brought the entire tank into the MRI scan room. The magnetic force of the MRI pulled the tank across the room, pinning the porter and MRI technologist to the machine. The porter suffered a fractured elbow, while the MRI tech, sustained severe lower abdomen injuries, including a punctured bladder and severe bleeding.

Hospital authorities launched an investigation, revealing that the incident was exacerbated by the failure of the MRI machine’s emergency shut-off switch. This malfunction lead to the men being trapped for four hours, during which they both lost consciousness and were treated for their injuries while still pinned. Rescuers, including a team of 20 people, attempted to free the tank using a rope. It was later reported that service engineers had removed the emergency shut-off switch from all the company’s MRI machines in India after a previous incident where a patient tampered with the switch, releasing a large amount of helium gas.

17. Knife Lodged in Patient’s Eye During MRI (November 2014 Auckland, New Zealand)

In November 2014, a man in his 70s suffered severe eye trauma at Middlemore Hospital in New Zealand after a knife flew out of his pocket during a brain scan and became lodged in his eye. The incident occurred when the man entered the MRI scan room with a belt, keys, and a closed knife in his pocket. The knife was drawn out by the powerful magnetic field of the MRI machine, striking him in the face and causing an orbital fracture and serious eye trauma.

“The pocketknife was attracted with force into the MRI scanner and hit him in the face, where it stayed due to the force of the magnetic field,” explained a hospital spokesperson. The man was immediately removed from the scanner, treated, and underwent a CT scan, which confirmed the extent of his injuries. Following the incident, the hospital reviewed its procedures and staff apologized to the patient. The brain MRI scan was successfully completed a few days later.

18. Cop’s Gun Stuck in MRI Machine During Burglary Investigation (February 2013 Illinois, USA)

In February 2013, an officer’s gun became stuck in an MRI machine at a Carol Stream doctor’s office, following a burglary investigation. The incident occurred at an office on the 600 block of East St. Charles Road when the officer entered the MRI room. The powerful magnet of the MRI machine pulled the officer’s gun away, leaving it stuck to the device. Since the magnetism could not be turned off, the gun remained in place, and access to the building was restricted. No injuries were reported, and the MRI manufacturer was called to assist with the situation. The incident happened while the officer was responding to a burglary call late at night. Carol Stream police confirmed that the burglary was under investigation.

19. Hoag Fined $50k After Patient on Metal Gurney Pulled into MRI (June 2010 California, USA)

In 2010, Hoag Hospital was fined $50,000 by the state Department of Public Health after an MRI patient on a metal gurney was magnetically pulled into the imaging machine. The CEO addressed the incident in a memo to staff, outlining the scenario and detailing policy changes to prevent future occurrences.

20. Off-Duty Officer in Florida Injured When Gun Pulled into MRI Machine (April 2009 Florida, USA)

In 2009, an off-duty police officer in Florida sustained a minor hand injury when her department-issued gun was pulled into an MRI machine. According to Jacksonville TV station WJXT, the injury occurred when their hand became trapped between the gun and the powerful MRI magnet.

21. The Rise of MRI Accidents (August 2005)

In 2005, incidents involving MRI scanners were reportedly on the rise, according to an article in The New York Times from August of that year. Dr. Moriel NessAiver, a physicist and assistant professor of radiology at the University of Maryland, highlighted these dangers. He teaches MRI safety to hospital personnel and demonstrated the risks of bringing metal objects into a room with powerful MRI magnets on “Good Morning America.”

22. Off-Duty Officer’s Gun Discharges in MRI Incident (August 2002 New York, USA)

In 2002, an article in the American Journal of Roentgenology detailed a serious incident involving an off-duty police officer at an outpatient imaging center in New York State. A miscommunication led to the officer bringing his firearm into the MRI scanning room. As he attempted to place the gun on top of a cabinet about a meter from the machine, the weapon was abruptly pulled from his grasp by the powerful magnetic field of the MRI scanner. The gun struck the left side of the machine and discharged a round into the wall at the rear of the magnet. The .45 caliber semiautomatic pistol was reportedly in a “cocked and locked” position, with the hammer cocked, thumb safety engaged and round in the chamber. Fortunately, no one was injured.

23. 6-Year-Old Dies After MRI Machine’s Magnetic Field Pulls Oxygen Tank (July 2001 New York, USA)

In July 2001, a tragic incident occurred at a New York-area hospital when a 6-year-old boy died after undergoing an MRI scan. The powerful magnetic field of the MRI machine pulled a metal oxygen tank across the room, striking and crushing the child’s head. The patient had been undergoing a routine imaging procedure following surgery for a benign brain tumor. The accident resulted in a fractured skull and severe brain injuries, leading to his death two days later.

Medical officials confirmed the patient was under sedation at the time of the incident. The hospital’s president and CEO expressed profound sorrow and took full responsibility for the accident, extending prayers and condolences to the child’s family. The incident occurred when the oxygen tank flew out of the hands of an anesthesiologist and was drawn toward the MRI machine, hitting the boy in the head.

24. Survey Reveals 52% of American MRI Facilities Report MRI Accidents (2001 USA)

In 2001, a survey revealed that only 52 percent of American MRI facilities reported accidents. Similarly, Canadian hospitals are not required to report problems with medical devices; they do so voluntarily. Health Canada is aware of only 11 MRI incidents from 1992 to 2002, compared to hundreds of cases in the US. According to officials, comprehensive screenings such as conducting orbit X-rays prior to MRI exams are taken to ensure no metal is present in the eye, as any metal could move during the scan, potentially causing the patient to lose their eye.

25. Woman Dies After Aneurysm Clip Shifts in MRI (1992 USA)

In 1992, a 74-year-old woman tragically hemorrhaged and died when an aneurysm clip in her brain shifted while she was on the MRI table. Exposure to the magnetic field caused the clip to move and lacerate the patient’s middle cerebral artery. Subsequent examination revealed that the aneurysm clip was magnetically active.

MRI Accidents Statistics

According to the US Food and Drug Administration (FDA) MAUDE incident reporting system , there have been over 2078 total reported cases to the FDA between January 2008 and June 2024 related to MRI machines.

MRI utilization statistics

The overall odds of an MRI accident are 0.35% (out of over 31.6 million MRI scans per year in the US), however safety incidents involving inpatients occur at a significantly higher rate of 0.74%, compared to the outpatient incident rate of 0.29%. Sedated patients are at the highest risk of injury during an MRI.

• Thermal burns account for over half of reported MRI accidents. Thermal events are the most common serious injuries (59% of reported incidents).
• Mechanical events, including slips, falls, crush injuries, broken bones, cuts, and musculoskeletal injuries, account for 11%.
• Projectile events make up 9%, while acoustic events represent 6% of the reports.
• The “Others” category includes PNS incidents, potential interruptions to patient monitoring equipment or accessories, incidents leading to equipment, building, or suite damage without causing injuries, reports filed by distributors, user facilities, manufacturers, incidents pending further inquiry, and adverse side effects.

Currently, the FDA receives around 500 adverse event reports per year for MRI scanners and coils from manufacturers, distributors, user facilities, and patients. Most of these reports detail heating and burns, with second-degree burns being the most commonly reported issue. Other reported problems include injuries from projectile events where objects are drawn toward the MRI scanner, crushed and pinched fingers from the patient table, patient falls, and hearing loss or tinnitus. Additionally, the FDA receives reports about image quality in MRI.

These accidents range from minor burns to life-threatening injuries, and in some cases, death. The FDA also reports that about 69% of MRI magnet accidents are caused by metallic implants or devices in the body, such as pacemakers, cochlear implants, and aneurysm clips.

The most notable detail regarding the case study is over 70% of these MRI accidents could have been prevented by adhering to MRI safety guidelines.

MRI burns

Burns may occur due to heating of metallic fibers in clothing, implants, the presence of foreign metal objects, or improper patient positioning. Other commonly recorded incidents include burns caused by sports clothing containing metal fibers that heat up in MRI, implants or equipment within or attached to the patient, and incorrect positioning of patients within the scanner.

Magnetic field risks

Electromagnetic fields in MRIs can dislodge or heat implants, induce electrical currents, and disrupt monitoring equipment, all of which may be included in reports.

Peripheral nerve stimulation (PNS) in MRI

Peripheral nerve stimulation (PNS) incidents vary based on patient conditions and magnet strength. PNS can reach up to 5% incidence of minor to serious PNS in a 3T MRI and above but rates are dramatically lower in 1.5T MRI systems and lower magnetic fields.

Contraindications

Contraindications for MRI include cardiac pacemakers, aneurysm clips, neurostimulators, implants, tattoos, permanent makeup, hair extensions, tissue expanders, and metal-containing clothing.

MRI death statistics

Some studies indicate that 0.17% of reported cases include patient deaths directly attributed to MRI safety incidents; however, this statistic is derived from a smaller case study of approximately 10,000 patients. Recent analysis of adverse events reported across the entire United States over the past decade shows an MRI death rate as low as 1 in 15,533,741 MRI cases. This figure is based on the total number of reported deaths attributed to MRI safety accidents per year divided by the number of MRI scans performed annually.

MRI Accidents Case Study Key Takeaways

MRIs can interfere with some cardiac pacemakers and other implanted electronic devices, even those made of non-magnetic metal.

To ensure safety, medical staff enforce the ‘no metal’ rule, which includes firearms—patient cooperation in following these guidelines is crucial to prevent serious, or even deadly consequences.

MRI magnets are always on, even at night, and cutting the power won’t turn them off. They rely on supercooled helium, which must be vented to shut down the magnet—a process that takes several minutes and comes with its own risks.

Patients should inform their doctor about any metallic implants or devices in their bodies before an MRI scan, including pacemakers, cochlear implants, and aneurysm clips. It’s also important to mention any recent surgeries, as metal sutures or clips might have been used.

It is essential to follow all safety guidelines and instructions provided by the MRI technician. This includes removing all metallic items such as jewelry, coins, and eyeglasses before entering the MRI room.

Patients should remain still during the scan to prevent any movement of protective padding and contact with MRI coils.

Lastly, It is recommended to undergo MRI scans only at accredited medical facilities and with experienced technicians who are trained in MRI safety protocols.

Most Common Causes of MRI Accidents

• Inadequate Screening: Failing to properly screen patients and personnel for metallic objects, implants, or devices can lead to serious accidents.
• Improper Use of Equipment: Not following the proper procedures for using MRI equipment, such as ensuring correct patient positioning and the use of non-conductive materials, can result in burns or image artifacts.
• Failure to Follow Safety Protocols: Skipping safety checks or ignoring established protocols for MRI operation, including not providing ear protection or monitoring sedated patients, increases the risk of accidents.
• Lack of Training: Insufficient training of MRI technologists and staff can lead to errors in handling the equipment and managing the MRI environment, leading to accidents.

MRI Accidents Frequently Asked Questions

In conclusion, MRI magnet accidents can be serious and even life-threatening. By being aware of recent cases and statistics, and following proper safety guidelines, individuals can help avoid such incidents and ensure their safety during MRI scans. If you have any concerns or questions about MRI scans, it is always best to consult with your doctor.
