When it comes to MRI patient transport, choosing the right device can dramatically affect both patient safety and workflow efficiency. MRI suites present unique challenges, including strong static magnetic fields, radiofrequency energy, and time-varying gradients. Selecting the proper MR Conditional stretcher or wheelchair is critical to ensure safe and effective transport. This guide compares MRI wheelchairs and stretchers from MRIMed, helping facilities choose the right solution for every patient scenario.
Understanding the Differences Between MRI Wheelchairs and Stretchers
Why Specialized MRI Transport Devices Are Needed
Traditional hospital equipment often contains ferromagnetic materials or conductive metals that can create hazards in MRI environments. Using standard wheelchairs or stretchers in an MRI suite can result in projectile accidents, RF heating injuries, or interference with imaging quality.
MRIMed MRI wheelchairs and stretchers are designed to eliminate these risks. For example, the MR Conditional 24-inch Wheelchair with Flip-up Arms & Removable Footrests is fully non-magnetic, tested for MRI conditions, and safe for patient transport within the MR suite. Similarly, the Non-Ferrous Height Adjustable Stretcher is built for smooth, safe patient transfers without introducing MR Unsafe components.
Key Safety Considerations for Patients and Staff
Patient safety depends on both device design and staff procedures. Key considerations include:
-
MR Conditional labeling: Devices must clearly indicate safe MRI conditions, including field strength, RF exposure, and spatial gradient limits.
-
Patient stability: MR Safe straps and backboards help secure patients during lateral transfers. MRIMed’s MRI Safe Backboard & Stretcher Straps ensure stability without risk.
-
Staff training: Personnel must be trained to recognize MR Conditional devices and avoid MR Unsafe items in the MRI suite.
Implementing these safety measures reduces the risk of injuries and ensures smooth workflow.
