To test if changing magnetic fields and radiofrequency fields used in nuclear magnetic resonance imagers could induce electrical currents capable of causing localized tissue heating in metal surgical clips and prostheses, steel surgical clips, copper wire clips, and hip prostheses were exposed to fields greater than those used in the nuclear magnetic resonance imager. Observations indicated that no significant heating should be expected from implanted surgical clips during exposure. The heating of larger metallic implants should be further investigated.
为了测试核磁共振成像仪中使用的变化磁场和射频场是否会在金属手术夹和假体中感应出能够导致局部组织发热的电流，将钢制手术夹、铜丝夹和髋关节假体暴露在比核磁共振成像仪中使用的场更强的场中。观察结果表明，在暴露过程中，植入的手术夹预计不会产生明显的发热。对于较大金属植入物的发热情况应进一步研究。
