MR Safe What does this mean?
MR Safe

MR Safe – an item that poses no known hazards in all MRI environments. Using the terminology, “MR Safe” items are non-conducting, non-metallic, and non-magnetic items such as a plastic Petri dish. An item may be determined to be MR Safe by providing a scientifically based rationale rather than test data.

MR Conditional

MR Conditional – an item that has been demonstrated to pose no known hazards in a specified MR environment with specified conditions of use. “Field” conditions that define the MR environment include static magnetic field strength, spatial gradient magnetic field, dB/dt (time rate of change of the magnetic field), radio frequency (RF) fields, and specific absorption rate (SAR). Additional conditions, including specific configurations of the item (e.g., the routing of leads used for a neurostimulation system), may be required.

MR Unsafe

MR Unsafe – An item that is known to pose hazards in all MRI environments. MR Unsafe items include magnetic items such as a pair of ferromagnetic scissors.

Frequently Asked Questions

1. What is the MRI safety status of the Angled Knee Wedge, Large?

The Angled Knee Wedge is designed for use inside the MRI suite and made from non-magnetic, non-conductive materials that won’t affect imaging quality or scanner function. It’s safe for use in MRI Zones III and IV, including during active scans. Always check your facility’s safety documentation or product labeling to confirm whether your specific unit is listed as MR Conditional and approved for use at your scanner’s field strengths (commonly 1.5 T or 3 T).

2. How does the angled design improve MRI patient comfort and image quality?

The wedge’s angled shape supports the knees and legs to promote neutral spine alignment, easing lower-back tension during scans. By keeping patients stable and comfortable, it helps reduce motion artifacts and improves image consistency—especially valuable in spine, pelvic, and lower-extremity MRI studies.

3. Can the Angled Knee Wedge be used with different MRI and imaging systems?

Yes. The Angled Knee Wedge, Large is compatible with a wide range of MRI tables and coil setups as well as other imaging systems like CT or ultrasound. Its lightweight, non-metallic construction makes it easy to reposition between procedures without introducing any magnetic interference.

4. What materials are used, and how should it be cleaned?

Each wedge is built with high-density, non-ferrous foam encased in a sealed medical-grade surface that’s simple to disinfect. It tolerates standard hospital-grade cleaners and disinfectants, such as quaternary ammonium or alcohol-based wipes. Avoid bleach or harsh solvents to preserve the surface over time.

5. What’s the difference between the Angled Knee Wedge and the Curved Knee Wedge?

The Angled Knee Wedge supports the legs on a gentle incline to ease back strain, while the Curved Knee Wedge cradles the knees in a rounded position for all-around comfort. Many imaging centers use both to match different scan types and patient needs.+
