HIFU: Another Alternative to Thyroid surgery for Thyroid Nodules?
What is HIFU? High Intensity Focused Ultrasound.It is dual focus of two sonar beams to a focal point to make heat. This heat is enough to destroy benign thyroid nodules. A recent study from Germany by Korkusuz et al looked at 12 patients with a single nodule up to 5 ml in volume. Treatment with a Echopulse HIFU probe resulted in 55% reduction in nodule size with a single treatment. It is a safe method of treatment but the size reduction was only 50%. It appears from this study that multiple treatments sessions will be needed, and that larger nodules > 5 ml would require too many sessions to get significant reduction.
Comment: There is a paper from the USA that is in review showing better reductions than 55% seen here. We await the publication one of the first studies on HIFU in the USA.
