射频消融术(radiofrequency ablation,RFA)是近年来发展迅速的一种非血管介入技术,尤其在肿瘤的微创治疗方面应用广泛,它通过各种实时影像技术的引导将射频电极置入肿瘤组织中,射频电极头发出射频波,使电极周围肿瘤组织中的离子震荡产生摩擦热,引起电极周边一定范 Radiofrequency ablation (RFA) is a rapidly developing non-vascular interventional technique in recent years. It is widely used in the minimally invasive treatment of tumors. It introduces radio frequency electrodes into the tumor tissue through various real-time imaging techniques , Radio frequency electrode RF hair waves, so that the electrode tissue around the tumor ion oscillation generated friction heat, causing the electrode around a certain range
