TSE images obtained around the lead using quadrature and implant-friendly (I F) patterns in the cadaver brain are shown. Quadrature pattern results in a signal loss mainly due to over-flipping of the spins at the vicinity of the lead. Axial image shows improved image quality as a result of using the I F pattern. In addition, I F pattern reduced the contact temperature significantly in comparison to quadrature excitation. Reprinted with permission from Magn Reson Med 2015; 73:1896–1903.
