Imaging guidewires in MRI is known to have heating hazards associated. In this work we show initial data that supports the use of local Tx coils over whole body coils for the safe imaging of standard guidewires with MRI. This was tested in vitro using parallel transmit (PTx) techniques to generate a scenario for a proper comparison between the two coil types. It was found that a local Tx coil produces less heating at the guidewire tip, than a body coil under comparable conditions.
