In MR safety, what does the term “MR Conditional” imply?

The term “MR Conditional” indicates that the safety of certain devices or implants in a magnetic resonance (MR) environment is dependent on specific conditions being met. This means that under certain circumstances, such as the strength of the magnetic field, the orientation of the device, or the presence of specific patient characteristics, the item may be considered safe for use in an MR environment.

For instance, an MR Conditional device may function safely in a specific type of MRI scanner but may not be safe in another type or at a higher magnetic field strength. Therefore, when using MR Conditional items, it is crucial to understand and adhere to the required conditions set forth by the manufacturer to ensure patient safety and device performance. This nuanced understanding is essential for MR safety professionals to evaluate the risks involved in MR procedures.
