New solutions, better training and regulation for reducing MR adverse events

“An outswing shielded door has zero impact on the full function of the device, which allows us to be flexible regardless of environment,” said Taylor. “This allows for ease of adoption by staff and trust in the device.”

Assure features the company’s Smart Alarm technology that prevents alarms from sounding due to door movement and a person exiting the room. Findings from Metrasens’ Technology Center study found that this technology can reduce extraneous audible alerts by 85%.

Iradimed Corporation also puts a big emphasis on addressing alarm fatigue. The company’s new Trusense technology features highly sensitive sensors that only alert when ferrous threats are heading toward Zone IV doors.

“All ferromagnetic detectors do a good job at detecting moving ferrous metal, however, not all moving ferrous metal is a Zone IV threat and the constant alarming causes alarm fatigue,” said Kevin Jirka, marketing director at Iradimed.

When it comes to hand-held screening solutions, Aegys Group’s CEIA PD240CH family of FMDs is the only one capable of screening for all metal while simultaneously differentiating whether it’s ferrous or non-ferrous.

“This level of information is extremely important to MR technologists who are responsible for preventing not just projectile incidents and RF-induced heating injuries to patients, but also for image quality and artifact suppression,” said Joe Barwick, founder of Aegys.

The company also offers its TechGate Auto solution, which is a modular robotic arm that provides a physical protective barrier. Barwick explained that this approach is superior to plastic chains or a retractable belt because it automatically deploys when the MR suite door is open.

Barwick believes that since there are advantages and disadvantages to every safety solution, the optimal approach is to utilize multiple, complementary solutions. Each should work cohesively to mitigate the risk of major or catastrophic incidents.

“There is the Swiss Cheese model of accident analysis that typically equates major or catastrophic incidents to a series of breakdowns in the safety model, wherein the inherent weaknesses in each layered solution systematically line up like the holes in slices of Swiss cheese to allow the incident to occur,” he explained.

He added that hand-held screening devices are ideal for nonambulatory or nonresponsive patients and when locating metallic objects. Fixed FMDs in Zone III provide standardized screening functionality and can be located away from the MR entrance where there is adequate time and space to address the screening process.
