How do we decide which patient is a candidate for thyroid RFA?
In 2012, the Korean Society of Thyroid Radiology made a consensus statement regarding the treatment of thyroid nodules with RFA.

Thyroid RFA is indicated either for patients with nodule-related symptoms or with hyperfunctioning nodule(s) which is causing thyrotoxicosis.
Confirmed to be benign with at least two separate US-guided fine-needle aspiration cytology and/or core biopsies.

In general, RFA is a safe procedure. However, we should be cautious in application of RFA in patients who are either pregnant or having history of serious heart problems.. Since there had been reports of cardiac complication during RFA for liver tumors, patients with serious heart disease should have continuous cardiac monitoring during and after RFA of thyroid nodules.
