Multimodal Imaging to Support Vim Targeting in Magnetic Resonance-Guided Focused Ultrasound Thalamotomy: Two Technically and Anatomically Challenging Cases

Essential tremor is the most common adult movement disorder, typically presenting with kinetic and postural tremor that interferes with daily activities. For patients unresponsive to medications, surgical options such as radiofrequency thalamotomy, deep brain stimulation, and magnetic resonance-guided focused ultrasound can provide therapeutic benefit.
