Background
MR scanning of electrically conductive implants is contraindicated without using device labels ''MR safe'' or ''MR conditional''. Devices that can be exposed to an MR environment must be tested for magnetically induced forces,
torques,
RF- and gradient induced interactions,
malfunction as well as MR image artifacts.
Standardized test methods are established.
Further standard development is work in progress e.g.
RF and gradient induced voltages,
vibration,
heating as well as functional electromagnetic interference issues.
Test results must be intelligibly transferred into a comprehensive implant labeling considering readability and adaptability for the current available user interface.
