Risk Assessment of Magnetic Resonance Imaging in Chronically Implanted Paddle Electrodes for Cortical Stimulation

Conclusion: MRI under the conditions described here seems to be safe with the implants used in this study. In particular, the induced temperature is much lower with paddle compared to conventional leads due to the different electrode design. The induced voltage does not carry any risks. However, these findings cannot automatically be transferred to other implants or other scanning conditions, and further studies are needed. The biomedical companies should be encouraged to develop MR-conditional paddle leads. Also, further research is necessary to study the mechanism of action of cortical stimulation in the future.Stereotact Funct Neurosurg 2015;93:182-189
