Radio frequency (RF) safety and image quality testing was performed in the presence of deep brain stimulation (DBS) electrodes using gel acrylamide phantoms and two 3T MRI scanners. Two electrodes, (Abbott and Medtronic) were tested with sequences including GRE, T1-weighted magnetization-prepared rapid gradient echo (MPRAGE), and T2-weighted turbo spin-echo (TSE). Safety testing showed low heating when electrodes were aligned along the B0 field (Z-axis) of the magnet, but higher heating when the electrodes were angled to the main field. Image quality testing showed smaller ferromagnetic susceptibility artifacts when electrode was parallel with B0 field and normal to transmit field.
