How did MR-Guided Focused Ultrasound become a breakthrough in Tremor Treatment?
ㅤ
The science behind MR-Guided Focused Ultrasound (MRgFUS) is the result of decades of research, combining advances in physics, functional neurosurgery, and diagnostic imaging.
ㅤ
The early foundations of focused ultrasound were laid in the 1950s, when researchers first explored the use of high-intensity sound waves to target tissue deep within the body. However, without accurate image guidance, its use in brain conditions was limited.
ㅤ
It wasn’t until the early 2000s that a major breakthrough occurred: real-time MRI guidance was paired with focused ultrasound. For the first time, clinicians could visualise the brain during treatment and guide ultrasound energy with sub-millimetre precision.
ㅤ
This led to the development of non-invasive thalamotomy, where focused ultrasound energy is used to create a tiny lesion in the ventral intermediate nucleus (VIM) of the thalamus—the region responsible for generating tremor in many patients.
ㅤ
In 2016, MRgFUS was approved by the FDA for treating Essential Tremor, followed by approval for Tremor-Dominant Parkinson’s Disease in 2018.
ㅤ
Since then, clinical studies have shown an average of 70% improvement in tremor severity for eligible patients, with durable outcomes and fewer risks than traditional surgical options like deep brain stimulation.
ㅤ
In the UK, Queen Square Imaging Centre is among the first to offer this pioneering treatment. Working alongside some of the country’s leading neurologists and neurosurgeons, our team forms part of a fully integrated movement disorder service.
ㅤ
Queen Square has also led advancements in imaging guidance, developing novel MRI sequences that improve targeting accuracy—helping to further enhance outcomes for our patients.

This incisionless, outpatient procedure is now one of the most significant innovations in the treatment of tremor—combining precision, safety, and lasting impact.
