How it works

Search any implant, review the MRI safety parameters, and verify against the manufacturer IFU before scanning.

1
Search

Type the implant name, manufacturer, or REF/UDI number from the Protheseausweis.

2
Review parameters

See MR status, max Tesla, field gradient, B×dB/dx, and dB/dt at a glance.

3
Verify with IFU

Always cross-check against the current manufacturer Instructions for Use before scanning.

For MRI technicians and radiologists

MR Safe — Device poses no known hazards in any MRI environment. No special conditions required. Safe at any field strength.

MR Conditional — Device can be safely scanned only under specific conditions: field strength (Tesla), spatial gradient, dB/dt, and SAR limits defined by the manufacturer. Exceeding any parameter is contraindicated.

MR Unsafe — Device poses unacceptable risks in any MRI environment. Do not scan. No conditions make it safe.

Remember: MR Conditional ≠ MR Safe. Always check the specific conditions (Tesla, gradient, SAR) before scanning. When in doubt, contact the manufacturer directly.

Understanding the parameters

Max Field Strength (Tesla)

The maximum static magnetic field (B₀) the device has been tested in. Most clinical scanners are 1.5T or 3T.

Spatial Gradient (T/m)

The maximum spatial rate of change of the static magnetic field. Determines the translational force on ferromagnetic components.

B × dB/dx (T²/m)

The product of the field strength and its spatial gradient. A combined measure of displacement force risk.

dB/dt (T/s)

The time rate of change of the magnetic field during gradient switching. High dB/dt can induce currents in conductive implants.
