We use fluoroptic thermometry to measure local heating near DBS electrodes implanted in pig's brain during 3.0T MRI. For IR SPGR and resting state fMRI sequences temperature changes of less then 0.3 were observed. These data could be valuable in assessment of safety during 3.0T MRI of patients with implanted DBS systems.
