Prevent Projectile Risks Before They Happen
Achieve next-level MRI safety with ferromagnetic detection systems that integrate effortlessly into your facility, helping you protect people, equipment, and compliance standards.
MRI environments are vulnerable to hidden ferromagnetic objects — from tools and oxygen tanks to surgical clips and implants. Even one missed ferromagnetic item can cause severe injury, equipment damage, or costly downtime. Metrasens’ ferromagnetic detection systems provide passive, contact-free protection across MRI zones, helping facilities:
Identify ferromagnetic materials on staff, equipment, or accessories before they reach the magnet room, preventing projectile incidents and costly downtime.
Use Metrasens Ultra in Zone II to detect hidden metallic fragments, surgical clips, or implants that may not appear in screening forms or patient records.
Proactively eliminate risks from ferromagnetic objects that could be drawn into the magnetic field, protecting patients, technologists, and MRI hardware.
Meet current MRI safety recommendations through validated ferromagnetic detection practices that support regulatory and accreditation requirements.
Reinforce a culture of MRI safety with layered detection, visible alerts, and ongoing staff awareness — ensuring every scan starts with confidence.
Metrasens Ultra provides a fast, non-contact way to detect ferromagnetic objects on or within patients before MRI scanning. Its sensitive, implant-safe technology allows technologists to identify hidden metallic fragments, surgical clips, or other retained ferromagnetic materials early in the screening process. Portable and radiation-free, Ultra is easy to deploy in patient prep or holding areas, helping prevent safety incidents, avoid emergency quenches, and reduce costly scan delays.
Ferroguard Assure delivers continuous, passive ferromagnetic detection at the threshold of your MRI suite, providing real-time alerts when ferromagnetic materials approach the magnet room. Designed specifically for MRI Zone III/IV boundaries, it operates safely without emissions or interference, ensuring protection for both patients and equipment. With reliable performance and configurable alerts, Ferroguard Assure helps staff prevent projectile incidents and maintain the highest standards of MRI safety across every scan.
Ferromagnetic detection supports MRI safety across every zone, from patient screening to magnet room access. Metrasens solutions provide layered protection tailored to each stage of the MRI workflow.
Zone II - Patient Screening
Use Metrasens Ultra to identify hidden or internal ferromagnetic risks, such as retained surgical clips or other ferromagnetic materials, before patients enter Zone III. This proactive screening step helps technologists confirm safety and prevent last-minute cancellations or incidents.
Zone IV - Magnet Room Entrance
Provide real-time detection of ferromagnetic materials approaching the MRI suite. Continuous monitoring alerts staff instantly, preventing unsafe items from entering the magnetic field and protecting both patients and equipment.
Multi-Scanner Facilities
Deploy consistent MRI safety protocols and ferromagnetic detection systems across multiple scanners or imaging locations, creating standardized, facility-wide protection and compliance.
“It is such a pleasure to work with Metrasens. I am most impressed with the sensitivity of their systems. They help keep our staff and our patients safe, and ultimately that’s what matters the most.”Dan SmockMRI Supervisor/MRSO, Children's Mercy
"Without Metrasens ferromagnetic detection systems, we would have never identified the presence of a magnet on our patient."Katherine Bushur, RT(R)(MR), BSRS, CRARadiology Manager, Children's Hospital Colorado
Ferromagnetic detection plays a vital role in maintaining MRI safety and preventing projectile incidents. The following questions address common considerations for implementing and optimizing ferromagnetic safety practices in MRI environments.
What is ferromagnetic detection in MRI Safety?
Ferromagnetic detection identifies magnetic materials — such as iron-based metals — that can become projectiles inside MRI environments. It’s a critical safety measure for preventing injuries and equipment damage.
How does Metrasens Ultra help in Zone II patient screening?
Metrasens Ultra detects ferromagnetic objects on or within patients before scanning, helping technologists identify retained metallic fragments or implants that could present safety risks.
What makes Ferroguard Assure different from other metal detectors?
Ferroguard Assure is purpose-built for MRI safety. It detects only ferromagnetic materials, minimizing false alarms and avoiding interference with MRI imaging.
Can these systems interfere with MRI equipment or images?
No. Both Metrasens Ultra and Ferroguard Assure are passive, non-emitting systems that have no effect on image quality or patient safety.
Are these solutions compliant with ACR and Joint Commission MRI safety standards?
Yes. Ferromagnetic detection directly supports recommended safety practices outlined by the American College of Radiology (ACR) and The Joint Commission, helping facilities demonstrate adherence to MRI safety requirements.
How does ferromagnetic detection support Joint Commission readiness?
Implementing ferromagnetic detection demonstrates proactive risk management and a commitment to maintaining a safe MRI environment — both of which align with Joint Commission expectations for safety compliance and documentation.
Can ferromagnetic detection systems assist with audit and incident documentation?
Yes. Many systems provide event logging and reporting capabilities, giving MRI leadership clear documentation for audits, safety reviews, and incident investigations. This helps strengthen regulatory readiness and continuous improvement efforts.
Do technologists need special training to use the systems?
Training is straightforward and provided during installation. Most staff become proficient within a short period, and continuing education options are available to maintain best practices.
