1614 – Magnetic resonance-guided focused ultrasound for the treatment of medically refractory essential tremor

Page last updated: 16 June 2021

Application Detail

Description of Medical Service

Magnetic resonance-guided focused ultrasound (MRgFUS) is a non-invasive, one-step method of targeted tissue thermal ablation used to treat medically refractory essential tremor (ET). The procedure combines focused ultrasound and magnetic resonance imaging to ablate the ventralis intermediate nucleus of the thalamus. The heat from MRgFUS causes a small lesion on the targeted spot on the thalamus, interrupting the abnormal activity associated with ET.

Description of Medical Condition

ET is a chronic, progressive neurological condition characterised by rhythmic and oscillatory tremors of the upper extremities, not attributable to another cause (e.g. Parkinson’s disease). Depending on disease severity, ET can lead to significant functional and social impairment.
