ikkeMRsikre

ikkeMRsikre is a term used in Norwegian radiology to describe objects, materials, or devices that are not safe to bring into or operate within an MRI environment. The term indicates that the item presents risks in the strong static magnetic field, RF energy, or rapidly changing magnetic fields used in magnetic resonance imaging. In practice, ikkeMRsikre items should be excluded from the MRI suite or removed from patients before scanning unless they have been properly assessed and cleared.

Examples of ikkeMRsikre items include ferromagnetic implants or instruments, some surgical implants, certain electronic devices, rods, screws, or other metal hardware, and external equipment that can move or heat up in the MRI. Clothing, jewelry, or other personal objects containing metal can also be non‑MRI‑safe. In addition, devices with unknown compatibility or inadequate labeling are treated as ikkeMRsikre until a safety assessment is performed.

The main risks associated with ikkeMRsikre objects are projectile injuries due to magnetic attraction, heating of conductive materials, malfunction or interference of medical devices, and imaging artifacts that degrade diagnostic quality. To minimize risk, patients and staff follow strict MR safety protocols, including pre-scan screening, removal of nonessential metal items, and verification of any implanted devices against MR compatibility guidelines.

In MR practice, objects are commonly categorized as MR Safe, MR Conditional, or MR Unsafe. IkkeMRsikre typically corresponds to MR Unsafe or untested items, and such items should not be brought into the MRI environment without appropriate safety clearance.
