Implanted electrodes in patients used to treat movement disorders can induce unsafe heating in scanners above 1.5T. However, this patient population will likely benefit strongly from having the option of high field and ultra-high field scanners. To remedy this situation, we demonstrate a proof-of-concept that by carefully selecting the weights of the B1 shim on a Siemens 3T Prisma scanner, negligible temperature rise can be obtained using a T2-TSE sequence. We also show that when no temperature rise is obtained, the image quality is better and more homogeneous.
