We report the results of MRI safety and image artifact assessment of a commercial deep brain stimulation (DBS) system implanted in an anthropomorphic phantom, undergoing MRI at 7T. RF heating was observed to be less than 2°C for all clinically relevant as well as worst-case configurations evaluated in the study. The magnetic force on the pulse generator was found to be within the safe limit. Metal-induced image artifact was comparable to what is observed at lower fields. Our results indicate that 7T MRI could be performed safely in patients with DBS implants under carefully evaluated device model and MRI hardware.
