Research progress of MRgFUS in the treatment of essential tremor

Abstract

Essential tremor (ET) is the most common movement disorder. In recent years, there has been no breakthrough of drug therapy. Therefore, surgical methods have played an important role in the treatment of ET patients with ineffective drug treatment. Magnetic resonance-guided focused ultrasound (MRgFUS) has been increasingly researched and applied in the treatment of ET as a good replacement therapy of surgeries, because it has such advantages as noninvasiveness, non-ionizing radiation, and intraoperative real-time monitoring of target temperature and morphology. The development history of MRgFUS treatment in ET, treatment principles, target selection, clinical efficacy, side effects, comparison with other surgical methods, deficiencies and prospects were briefly reviewed in this article.
