Magnetic resonance imaging and surgical clips
Abstract:
Magnetic resonance imaging produces diagnostically useful images of soft-tissue structures within the body. Implanted magnetic materials degrade these images and are subject to magnetic forces from the imaging process. The authors evaluated 54 surgical clips (38 aneurysm and 16 hemostatic) for compatibility with magnetic resonance imaging. From their findings, they recommend that the use of ferromagnetic clips be discontinued and that until this is accomplished, a record of the type of clips used be noted so that the patient is not placed at risk by the use of magnetic resonance imaging or deprived of the diagnostic benefits associated with its use.
Insights
Ferromagnetic surgical clips can interfere with magnetic resonance imaging (MRI) and pose risks to patients. Discontinuing their use is recommended to ensure safe and effective diagnostic imaging.
Area of Science:
- Medical Imaging
- Biomaterials Science
Background:
- Magnetic resonance imaging (MRI) is crucial for soft-tissue diagnostics.
- Implanted ferromagnetic materials can cause artifacts and safety concerns during MRI.
Purpose of the Study:
- To evaluate the magnetic resonance imaging compatibility of surgical clips.
- To assess the risk of ferromagnetic surgical clips during MRI procedures.
Main Methods:
- The study assessed 54 surgical clips (38 aneurysm, 16 hemostatic) for MRI compatibility.
- Compatibility was evaluated based on image degradation and magnetic force effects.
Main Results:
- Ferromagnetic surgical clips were found to degrade MRI images.
- These clips are subject to magnetic forces during MRI, posing potential risks.
Conclusions:
- The use of ferromagnetic surgical clips should be discontinued.
- Maintaining a record of clip types is essential for patient safety during MRI if discontinuation is not immediate.
