Magnetic resonance (MR) guidance of microwave ablation of hepatic tumors could help to overcome poor visualisation of the ablation zone by ultrasound, may allow better intraprocedural confirmation of technical success. The ablation applicator is a metallic rod and can potentially act as an ‘antenna’ during MR imaging which can produce unwanted localized heating in nearby tissue. In this abstract, we investigated via electromagnetic simulations the maximum SAR10g changes caused by applicators of different radius and length and for various insertion angles.
