Metrasens promotes MR safety data management solution and implant detection study

Lisa Chamoff, Contributing Reporter | December 03, 2018
MR safety company Metrasens is moving beyond simple ferromagnetic detection and alerts to a more comprehensive risk management solution that uses data to help facilities avoid adverse incidents.

At the 2018 RSNA annual meeting, the company showcased its new data management system, which allows imaging professionals the ability to see the big picture of key MR safety metrics.

Metrasens’ Safety Suite works with the company’s Ferroguard systems, which detect ferrous objects, to show key data points, such as how often those objects enter the MR suite and how long doors to scanning rooms are left open.

“This has never been available for MR facilities before,” Colin Robertson, senior vice president for sales and marketing at Metrasens, told HCB News.

The metrics are available via a web portal and an Android app.

Robertson said that Children’s Hospital of Colorado has shown a reduction in ferrous entries since using Metrasens’ Safety Suite.

The company also publicized new research on the use of its patient screening systems to detect implants. For the study, published in the September issue of the Journal of Magnetic Resonance Imaging, Metrasens collaborated with the Mayo Clinic to look at 75 outpatients who had pacemakers.

The results showed that the screening system detected all pacemakers, while a control group of 68 patients without pacemakers did not cause an alert.

Mark Keene, the chief technology officer for Metrasens, said some pacemakers were very strongly detected and some were weakly detected, but there was no difference between pacemakers that are safe for use in MR and ones that aren’t.

Keene said they are looking to expand the research into other types of implants.

Metrasens is not able to market their system for pacemaker detection as that would require FDA approval, but wanted customers to know that the system provided an extra layer of protection from surprises, in case a patient forgets or fails to mention that they have an implant.

“We’re making our customers aware that it can detect implants as well,” Keene told HCB News. “Customers are looking to detect unexpected items.”
