Coherent Structural and Functional Network Changes after Thalamic Lesions in Essential Tremor.

Background: Magnetic resonance-guided focused ultrasound of the ventral intermediate nucleus is a novel incisionless ablative treatment for essential tremor (ET).

Objective: The aim was to study the structural and functional network changes induced by unilateral sonication of the ventral intermediate nucleus in ET.

Methods: Fifteen essential tremor patients (66.
