Focused ultrasound is a new, scalpel-free treatment for essential tremor, the most common movement disorder. A UVA team led by Jeff Elias, MD, pioneered this approach in the United States. We’re among a select few programs in the country that can offer this treatment.
What is Focused Ultrasound?
Focused ultrasound combines high-frequency (ultrasound) energy with magnetic resonance imaging (MRI). This treatment safely and accurately treats tissue deep within the body without the need for incisions. Elias led a multi-site clinical trial to demonstrate the safety and effectiveness of this approach for treating essential tremor. Researchers are exploring other potential applications.

How Does Focused Ultrasound Work?
Focused ultrasound disrupts the brain activity responsible for the tremors while protecting normal, healthy tissue.
What to expect:
- Your doctor uses MRI to accurately target brain tissue and electrical activity responsible for the tremors
- Your doctor guides concentrated beams of ultrasound energy to the treatment area
- The energy beams disrupt the abnormal electrical activity and relieve your symptoms
What Are the Side Effects?
- Mild numbness or tingling in the fingertips or lips on the side of the body getting treated
- Unsteadiness after the procedure
- Minor side effects, such as headache, pain, warmth and/or dizziness
- Major side effects, such as stroke, infection or seizures, although the risk for experiencing these is very low
Can I Receive Focused Ultrasound for Other Neurological Disorders?

Currently, focused ultrasound is only available for essential tremor. We also care for patients from around the world with rare and complex neurological disorders, including Parkinson’s disease and brain tumors.
If I Have Essential Tremor, Does This Mean I Can Receive Focused Ultrasound?
Focused ultrasound is not available for people with certain medical conditions, such as kidney disease, or those who can’t undergo an MRI because they have an implantable medical device, like a pacemaker.
Your doctor will discuss the best treatment option for you, including alternatives such as deep brain stimulation.
Do I Qualify for a Focused Ultrasound Thalamotomy?
Focused ultrasound thalamotomy is a special focused ultrasound procedure that can be very effective for managing ET. Your care team will evaluate you as a potential candidate for this procedure.
Patient selection typically depends on:
- Confirmed diagnosis of ET
- ET has not gotten better with medications such as propranolol or primidone
- ET is severe enough to consider a surgical procedure
- ET limits your ability to perform daily activities at home or at work
- Patients who are deemed potential candidates for focused ultrasound thalamotomy will also need to undergo a special CT scan as part of their evaluation. Because of this, you may be excluded from focused ultrasound thalamotomy if you have a pacemaker or other implanted device.
- If you are prone to anxiety or claustrophobia, you may have trouble tolerating the 2-3 hour procedure.
What is the Likelihood of Tremor Recurrence?
There is always a chance that the focused ultrasound thalamotomy procedure might not work or that the effects will wear off with time. We are unable to guarantee the result or provide refunds for the procedure if it is ineffective.
Is Focused Ultrasound Covered by My Insurance?
The FDA approved the approach in July 2016, but it’s not yet covered by insurance.
How Much Does Focused Ultrasound Cost?
Call 434.924.0451 for pricing information.
When Will You Start Treating Patients Using Focused Ultrasound?
We are currently only accepting patients who can pay out of pocket. We’re working on making this available for more patients, it’s undetermined when private insurers will begin covering this procedure. In the meantime, our physicians continue to see patients and advise them on the best options for their condition.
