Ferroguard® Screener

MRI SAFETY - SEE THE UNSEEN

DETECTING RISK ITEMS THAT OTHER SYSTEMS MISS

Fast, effective, Zone II screening to prevent incidents from the smallest, hidden items.

Despite careful, guideline compliant screening procedures, small ferrous objects inadvertently concealed on a patient, visitor or staff member may present a significant risk within your MRI facility.

Ferroguard Screener by Metrasens is the most sensitive ferromagnetic detection system (FMDS) for MRI safety available providing whole body screening with superior detection.

Detection performance comparison – smaller risk items

DETECT THE RISKS OTHER SYSTEMS MISS

Independent testing-laboratory study8 comparing the performance of Ferroguard Screener in detecting smaller, commonly encountered risk items, against the performance of the other most frequently seen whole-body FMDS.

Only Ferroguard Screener uses Fluxgate sensors, making it the most sensitive FMDS available (minimum detectable magnetic signal, 80 pTesla, 0.8 μGauss). Despite its compact design, it’s super-sensitive to smaller risk-items all the way from the top-of-the-head to the tip-of-the-toes of the tallest patient.

DEMONSTRATED IMPLANT DETECTION EFFICACY

Reported detection of implanted cardiac pacemakers in 75 patients1:
– 99.6% Sensitivity
– 100% Specificity
Similar detection efficacy demonstrated for a wide range of implanted ferromagnetic items2-5

ferromagnetic detector implants

INCREASING THROUGHPUT AND EFFICIENCY

Published studies show 5% of patients still have remaining, unknown, ferromagnetic risk items following diligent conventional screening and gowning6,7. Adopting Ferroguard Screener as an additional, final step in your patient screening process can reduce artifacts and time-wasting restarts.

With multiple professional and accrediting bodies involved, it can be difficult to keep track of what the various published safety recommendations and guidelines in the US say. Metrasens is pleased to assist by providing this summary of the present status as it relates to the growing adoption of ferromagnetic detection systems (FMDS) for the prevention of MRI projectile incidents.

Ferroguard should not be used to replace current MRI screening procedures. The safety of staff and patients is best served by the combination of conscientious screening protocols, thorough staff training AND installation of a ferromagnetic detection system used in the correct manner.
