A selection of commonly used metal ossicular prostheses were tested to see if they were attracted by the 5000-gauss magnetic field of a magnetic resonance imager. None of the prostheses tested was attracted by the magnetic field. Using a model system, it was found that some of the metal objects perturbed the magnetic field, thus affecting the image produced by the scanner. Therefore, while metal implants may be safe in a powerful magnetic field, they can alter the field, resulting in abnormal images.
对一些常用的金属听小骨假体进行了测试，以确定它们是否会被磁共振成像仪5000高斯的磁场吸引。所测试的假体均未被磁场吸引。通过一个模型系统发现，一些金属物体扰乱了磁场，从而影响了扫描仪生成的图像。因此，虽然金属植入物在强磁场中可能是安全的，但它们会改变磁场，导致图像异常。
