MRI is one of the safest diagnostic imaging modalities available. But MRI safety statistics tell a more nuanced story — preventable incidents continue to occur, resulting in patient injuries, equipment damage, and regulatory consequences. As MRI Safety Week 2026 approaches (July 27–31), here are 10 MRI accident statistics every technologist, radiology manager, and safety officer should know.
Stat #1: ~40 Million MRI Scans Performed Annually in the US
The US performs roughly 40 million MRI exams each year, a number growing at 3–4% annually. That volume means even a tiny error rate produces hundreds of incidents. At high-volume imaging centers running 30+ scans per day, the cumulative exposure to risk is substantial. More scans mean more patient handoffs, more screening decisions, and more opportunities for safety lapses — making robust pre-MRI screening protocols essential at every facility.
Stat #2: ~600 MRI Adverse Events Reported to the FDA Annually
The FDA's MAUDE database logs approximately 600 MRI-related adverse event reports each year — projectile events, thermal burns, implant complications, and acoustic injuries. The critical caveat: these are only reported incidents. Actual numbers are believed to be significantly higher, as many near-misses go unreported.
Stat #3: Projectile Incidents Are the #1 Reported MRI Safety Event
Projectile incidents — ferromagnetic objects accelerated into the bore — consistently rank as the most common MRI safety event. Oxygen tanks, IV poles, wheelchairs, and cleaning equipment have all been involved, some causing severe injury or death. Virtually all are preventable through proper screening before entering Zone IV. Read more about real projectile incident cases and their lessons.
Ferromagnetic detection systems are the most effective countermeasure. Browse MRI Med's MRI Safety collection to find ferromagnetic detectors, screening tools, and warning signage for your facility.
Stat #4: Only ~30% of US MRI Facilities Have Ferromagnetic Detection
Despite being the most effective projectile prevention technology, ferromagnetic detection systems are installed in only about 30% of facilities. Cost is the primary barrier, though prices have dropped significantly. A single projectile incident can cost hundreds of thousands of dollars — far exceeding the price of a detection system. The ACR is increasingly moving toward requiring detection, and facilities should evaluate their workflow against the MRI safety equipment checklist.
Stat #5: RF Burns Account for ~20% of MRI-Related Injuries
Radiofrequency burns represent roughly 20% of reported MRI injuries, caused by improper coil placement, skin-to-skin contact creating conductive loops, or tattoo ink with metallic pigments. Prevention relies on meticulous patient positioning, padding, and thorough pre-scan screening. Proper use of MRI imaging aids can significantly reduce burn risk.
Stat #6: 3.5 Million+ Americans Have MR Conditional Implants
Over 3.5 million US patients have MR Conditional implants — cardiac pacemakers, orthopedic hardware, neurostimulators — that can only be safely scanned under specific manufacturer-defined conditions. "MR Conditional" does not mean "MR Safe." Deviating from specified parameters can cause device malfunction or tissue heating.
Stat #7: ~60% of MRI Safety Incidents Involve Human Error
Equipment failures grab headlines, but approximately 60% of MRI safety incidents stem from human error — inadequate patient screening, failure to follow established protocols, rushing through safety checks, poor communication during shift changes, and insufficient training. This underscores a fundamental truth: technology alone cannot make an MRI suite safe. Facilities that invest in regular, documented MRI safety training and empower staff to pause workflows when something seems wrong report consistently fewer incidents. Use MRI Safety Week as a catalyst to refresh your team's safety habits.

View Trusted ProductsStat #8: 50%+ of MRI Facilities Have at Least One Safety Deficiency
ACR accreditation data shows more than half of MRI facilities have at least one safety deficiency — inadequate zone signage, outdated screening forms, incomplete training records, or improperly stocked emergency equipment. Many are easy to fix once identified. Our MRI Safety Audit Checklist for 2026 provides a step-by-step framework, and you can review common MRI safety violations for the most frequent issues.
Stat #9: MRI Insurance Claims Average $250,000–$500,000
MRI-related liability claims average $250,000 to $500,000, with serious injury cases reaching well into the millions. These figures encompass patient care costs, equipment damage, legal fees, and reputational harm. For context, a comprehensive suite of MRI safety equipment — ferromagnetic detectors, signage, and screening tools — costs a fraction of a single moderate claim. The ROI on safety equipment isn't hypothetical; it's mathematical.
Stat #10: Facilities with MRI Safety Officers Report 60% Fewer Incidents
Facilities with a dedicated MRI Safety Officer (MRSO) report roughly 60% fewer incidents. The MRSO provides centralized accountability for training, audits, incident response, and vendor coordination — transforming safety from a diffused obligation into a measurable program. Our 5-Day MRI Safety Week Activity Plan includes guidance on establishing this role.
What These MRI Safety Statistics Mean for Your Facility
The common thread: the vast majority of MRI safety incidents are preventable. They result from gaps in screening, training, equipment, and culture — gaps that can be closed with deliberate effort. Whether it's installing ferromagnetic detection, updating screening forms, or scheduling quarterly drills, prevention pays for itself many times over.
Turn These MRI Safety Statistics Into Action
From ferromagnetic detection systems and MRI safety signs, labels, and screening tools to MR Conditional patient transport equipment and non-magnetic tools, MRI Med carries everything your facility needs to stay compliant and protect patients.
Browse MRI Med's MRI Safety collection to find ferromagnetic detectors, zone signage, safety labels, and screening accessories — and take a proactive step before MRI Safety Week begins.
Conclusion
Numbers tell the story, but action writes the ending. The MRI safety statistics outlined above aren't meant to alarm — they're meant to inform and drive meaningful improvement at your facility. Use MRI Safety Week 2026 as your catalyst: share these stats with your team, conduct an internal audit with our 2026 safety audit checklist, and make one tangible improvement this week. After Safety Week wraps up, check our MRI Safety Week 2026 recap for highlights, resources, and next steps.
The data is clear. The solutions are available. The only variable left is action.
Frequently Asked Questions
How many MRI accidents happen each year?
Approximately 600 MRI-related adverse events are reported to the FDA annually through the MAUDE database. Actual numbers are believed to be higher, as many near-misses go unreported.
What is the most common MRI safety incident?
Projectile incidents — ferromagnetic objects pulled into the scanner's bore — are the most commonly reported event, followed by RF burns (~20% of injuries). Both are largely preventable with proper screening and training.
How can I reduce MRI safety risks at my facility?
Install ferromagnetic detection systems, conduct regular safety audits, maintain current screening protocols, invest in staff training, and designate a dedicated MRI Safety Officer. Our MRI safety equipment checklist is a practical starting point.
Where can I find MRI safety incident data?
The FDA's MAUDE database is the primary public source for reported MRI adverse events. The ACR publishes safety guidance, and organizations like the ISMRM present safety data at annual meetings. Bookmark our MRI Safety Statistics 2026 post for a curated overview.
