Safety Testing of Performing MRI Scans with Implanted Soletra Pulse Generator at 3 Tesla

We have performed safety testing of running MR scans with active Soletra 7426 implantable pulse generator (IPG) at 3 telsa. Performing anatomical and functional MRI scans using a 3 tesla whole body Siemens Total Imaging Matrix Trio system with a circularly polarized transmit/receive head coil of a gel phantom with the IPG placed in the gel with a pair of 3387-40 leads, we did not measure any significant heating at any lead contacts or the IPG case. The temperature measurement was done using fluro-optic cables, and the ON/OFF state of the IPG was constantly monitored externally by voltage measurement.
