High power ultrasound can be focused on a targeted point to raise the temperature to 70-80°C.
HIFU uses sonication (sound energy) to create this heat. Each sonication heats only a small focal target, so the interventional radiologist will use multiple sonications to ablate the whole affected area. The interventional radiologist may use diagnostic sonography with focused ultrasound (USgFUS or USgHIFU) or magnetic resonance guidance with focused ultrasound (MRgFUS).
You may be advised to have the procedure to treat uterine fibroids or to alleviate pain from bone cancer. HIFU can also be used to treat prostate cancer, both as a primary treatment and after radiotherapy.
Investigations into using HIFU to treat liver, breast and brain tumours have had promising results.
Positive results with transcranial MR-guided focused ultrasound surgery (tcMRgFUS) as a non-invasive treatment of essential tremors, neuropathic pain and Parkinson’s disease have been reported in literature. There have also been some investigations into the use of HIFU for temporarily opening the blood-brain barrier, allowing absorption of drugs into the brain.
A minimally invasive catheter-based system designed to ablate heart tissue responsible for a trial fibrillation has been approved for use in Europe and is undergoing an FDA approved trial in the United States.
You should see results within the first 20 days after the treatment. Results will continue to improve in the following weeks.
This is common HIFU FAQ. It is important to remember that this will vary from person to person. Results can last for up to 6 months. If you take care of your skin, then you will see long-lasting effects from just one treatment!
