Introducing MRI-guided Focussed Ultrasound

St Vincent’s hospital is pleased to now offer Neuravive, a new MRI-guided noninvasive treatment for essential tremor. Using 1024 beams of ultrasound energy all pinpointed on the area responsible for the tremor, Neuravive is providing immediate and significant reduction in tremors.

How It Works

The Technology Behind MRI-guided Focussed Ultrasound

What is Essential Tremor?

Essential (and dystonic) tremor can worsen over time, but are not related to Parkinson’s Disease. A movement disorder specialist can help confirm the diagnosis, but one of the common differences with a tremor caused by Parkinson’s disease is that it tends to be worst when not moving and decreases when actively doing something with the arms (whereas the reverse is true in essential and dystonic tremor).

Other causes of tremor can include thyroid problems, certain medications, and multiple sclerosis. Essential and dystonic tremor tremor can occur at any age, even in childhood. Medications are sometimes effective for tremor but only around half of people obtain significant benefit. Essential and dystonic tremor often gradually worsen over the years.

The Neuravive Procedure

The Neuravive procedure is a non-invasive treatment that reduces tremor. It is based on MR-guided Focussed Ultrasound (MRgFUS) technology which combines High Intensity Focussed Ultrasound that is guided by Magnetic Resonance Imaging (MRI).

During the Neuravive procedure, the patient is fully conscious and ultrasound waves pass through the brain without the need for an incision. These ultrasound waves are focussed on a specific point in the thalamus to destroy the tremor causing cells. The whole procedure is monitored by MRI in real time and by the neurologist repeatedly checking the patient and their tremor. When it is over, there is a significant and immediate reduction in tremor.
