Ensuring safe imaging around metallic implants is paramount to safety in MRI. Parallel transmission offers the possibility of electromagnetically decoupling metallic implants from an RF coil. Here the impact of the number of transmit channels used is assessed in terms of reduction of SAR around the implant and improvement in the homogeneity of the B₁⁺ imaging field.
