MRI presents several potential risks for patients with implanted devices and one of the main concerns is RF induced heating of devices and nearby tissues. The aim of this study was to compare the RF induced heating characteristic of wires at 1.5T and 3T using simulations and direct measurements. Greater heating (SAR amplification) can be observed at lower field strengths for longer wires.
