In radiofrequency ablation, imaging techniques such as ultrasound, computed tomography (ct) or magnetic resonance imaging (MRI) are used to help guide a needleelectrode into a cancerous tumor.
For a large tumor, it may be necessary to do multiple ablations by repositioning the needleelectrode into different parts of the tumor to ensure no tumor tissue is left behind.
对于一个大的肿瘤，它可能需要通过到不同肿瘤部位的电极针做多次消融，以确保没有留下肿瘤组织。

At the end of the procedure, the needleelectrode will be removed and pressure will be applied to stop any bleeding and the opening in the skin is covered with a dressing.
