MRkompatibilitet

MRkompatibilitet refers to the compatibility of medical devices with Magnetic Resonance Imaging (MRI) procedures. It is a critical safety consideration for patients undergoing MRI scans, as certain materials or electronic components can interact dangerously with the strong magnetic fields and radiofrequency pulses used in MRI.

Devices are typically classified into categories based on their MR compatibility. MR Safe devices pose no known hazards in the MR environment. MR Conditional devices are safe under specific conditions, such as when used with a particular MRI scanner field strength or when certain components are secured. MR Unsafe devices present unacceptable risks in the MR environment and should not be brought near an MRI scanner.

Manufacturers of medical devices are responsible for testing and labeling their products for MR compatibility. This labeling is crucial for healthcare professionals to ensure patient safety. Common implantable devices that require careful consideration include pacemakers, cochlear implants, and neurostimulators. Non-implantable devices like infusion pumps and ventilators also need to be evaluated.

Failure to assess MR compatibility can lead to serious adverse events, including device malfunction, heating, displacement, and potential injury to the patient. Therefore, a thorough understanding and adherence to MR compatibility guidelines are paramount for safe medical practice. Healthcare facilities typically have strict protocols in place for screening patients and their medical devices before an MRI examination.
