Magnetic Resonance-Guided Focused Ultrasound (MRgFUS) for Movement Disorders: A Practical Guide for Neurologists.

Magnetic resonance-guided focused ultrasound (MRgFUS) is a novel, noninvasive therapeutic approach that shows potential in treating movement disorders, such as essential tremor, Parkinson's disease, and dystonia. This technique combines high-intensity focused ultrasound with real-time magnetic resonance imaging, allowing for accurate targeting and thermal ablation of deep brain areas without incisions or exposure to ionizing radiation. MRgFUS provides precise lesioning with intraoperative feedback, enabling immediate assessment of symptoms. Clinical trials and initial clinical applications have shown significant enhancements in motor symptoms and quality of life, boasting a favorable safety profile with fewer adverse effects compared to traditional surgical methods like deep brain stimulation (DBS). For patients who are not candidates for surgery or who prefer less invasive treatments, MRgFUS represents a valuable alternative. This brief overview serves as a useful resource for general neurologists.
