Vital Signs Monitor Overcomes the MRI Environment

An innovative magnetic resonance imaging (MRI) compatible vital signs monitor allows patients to be supervised during imaging.

The Iradimed (Winter Springs, FL, USA) 3880 MRI compatible patient monitoring system is a compact, lightweight device designed to facilitate transportation of patients from a critical care unit to the MRI scanner and back, increasing patient safety by ensuring uninterrupted vital signs monitoring and decreasing the amount of time critically ill patients are away from their care units. The system features a 30,000 gauss rating in a non-magnetic construction with a small form factor, which means it can operate virtually anywhere in the MRI scanner room.


An optional paired tablet allows for remote viewing of patient vital signs and control of the monitoring unit from within the MRI control room. Additional features include wireless electrocardiogram (ECG) with dynamic gradient filtering; wireless oxygen saturation (SpO2) using Masimo algorithms; respiratory CO2; non-invasive blood pressure and patient temperature measurement; and optional advanced multi-gas anesthetic agent unit featuring continuous minimum alveolar concentration measurements.

“The Iradimed 3880 monitor’s compact non-magnetic design positions Iradimed as the only company in the world with a MRI compatible patient monitor that can be used to transport patients from the critical care departments of hospitals to the MRI scanner room and back to critical care,” said Roger Susi, President and CEO of Iradimed. “It has an easy-to-use design and unique wireless tablet remote control that allows for the effective communication of vital signs information to clinicians.”

The MRI Compatible definition is typically applied to devices not considered to significantly affect the quality of the diagnostic information, nor have their operations affected by the MRI scanner. The MRI conditions in which the device was tested need to be specified, since a device which is safe under one set of conditions may not be found to be so under more extreme MRI conditions.
