It is demonstrated that parallel transmit (PTx) can be used to both safely visualise tissue (no heating even from high SAR sequences), and safely visualise a wire by direct coupling using low power MR sequences. A low power version of a TSE sequence was found to give the best depiction of the wire when using this method.
