nonMRkompatible

nonMRkompatible is a term used to describe devices or materials that are not magnetic resonance (MR) compatible. This means they cannot be safely used in or near an Magnetic Resonance Imaging (MRI) scanner. The primary concern with non-MR compatible items is the strong magnetic field generated by the MRI scanner.

When a non-MR compatible item is brought into an MRI environment, it can pose several risks. Ferromagnetic materials, which are strongly attracted to magnets, can be pulled with significant force towards the scanner. This can lead to serious injury to patients or staff if they are holding or are in close proximity to the object. Such objects can become projectiles, causing blunt force trauma or lacerations.

Additionally, some electronic devices that are not MR compatible may malfunction or be damaged by the radiofrequency pulses used in MRI. This can lead to inaccurate imaging or complete failure of the device. Certain implants or medical devices, even if not strictly ferromagnetic, might have components that can heat up significantly due to the radiofrequency energy, posing a risk of thermal injury to the patient.

Therefore, it is crucial to identify and exclude all non-MR compatible items from the MRI suite. Hospitals and imaging centers have strict protocols for screening patients, visitors, and staff for such items before they enter the scanner room. Signs are typically posted outside MRI suites to warn individuals about the strong magnetic field and the need to remove metallic objects. Items are often categorized with MR conditional or MR unsafe labels to guide their use in the MRI environment.
