What is HiFu

High-Intensity Focused Ultrasound (HiFu)

High-intensity focused ultrasound (HiFu) is a non-invasive, single day procedure in which we harness the power of acoustic energy to create a lesion in your brain along a pathway that is responsible for causing tremor. Immediate tremor relief is obtained with minimal side effects, where 75% of patient see years of lasting tremor improvement. This is not a surgical intervention.

Who is eligible
Patients with diagnoses of Essential Tremor and tremor-dominant Parkinson’s disease are eligible as per the FDA, and must be over the age of 22.
How it works
Using an MRI scanner and ultrasound waves, HiFu targets a small node within the brain along a pathway that is causing tremors. This allows us to closely pinpoint and lesion, or destroy, this brain area about the size of a pea. Only the specific target area is destroyed, without harming surrounding tissue.
What to expect

  • Before: We will order an MRI and CT scan, and/or other imaging, to measure the shape and thickness of your skull to ensure that you are a candidate for this procedure. 

  • During: While fully awake, you’ll be placed inside an MRI scanner from mid-torso up with your head positioned inside a frame to prevent movement. The bed will move in and out, so that we can continually assess you throughout the treatment. This procedure typically last less than 1.5 hours.

  • After: Once the HiFu session is completed, you’ll experience immediate relief from your symptoms. Recovery time differs, but patients typically resume normal activities within a few days.
