Neuromodulation such as stereotactic lesioning surgery and deep brain stimulation (DBS) has been used for decades for management of advanced movement disorders. Unfortunately, these surgical treatments are associated with complications such as intracerebral haemorrhage, infections, damage to adjacent structures and are less acceptable by the elderly patients. Recently, magnetic resonance imaging (MRI) - guided focused ultrasound (MRgFUS) surgery has been introduced as a novel surgical treatment for advanced movement disorders, namely essential tremor and tremor dominant Parkinson's disease.
In this presentation, I am going to discuss the principle of MRgFUS in the management of movement disorders. I will also review the literature on MRgFUS in movement disorders and compare its use with DBS. Besides, I will go through patient selection criteria and post-operative treatment.
